A 62 kg male ice skater is facing a 42 kg female ice skater. They are at rest on the ice. They push off each other and move in opposite directions. The female skater moves backwards with a speed of 3.7 m/s. What is the velocity of the male skater?
The velocity of the male skater is 2.5 m/s in opposite to the direction of the female skater moving.
What is the law of conservation of momentum?According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced. As a result, momentum cannot be gained or lost.
Given parameters:
The mass of the male ice skater is: M = 62 kg.
The mass of the female ice skater is: m = 42 kg.
Initially both of them are in rest.
After they push off each other and move in opposite directions, the female skater moves backwards with a speed of v =3.7 m/s.
Let the speed of the male ice skater is V m/s now.
From the law of conservation of momentum:
MV + mv = 0
V = - mv/M
= - (42×3.7)/62 m/s
= - 2.5 m/s
Hence, the velocity of the male skater is 2.5 m/s in opposite to the direction of the female skater moving.

Define potential energy (PE)
Answer:
Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system.
This form of energy has the potential to change the state of other objects around it, for example, the configuration or motion.
Various forms of energy can be grouped as potential energy.
Each of these forms is associated with a particular kind of force acting in conjunction with some physical property of matter (such as mass, charge, elasticity, temperature etc).
For example, gravitational potential energy is associated with the gravitational force acting on object's mass; elastic potential energy with the elastic force (ultimately electromagnetic force) acting on the elasticity of a deformed object; electrical potential energy with the coulombic force; strong nuclear force or weak nuclear force acting on the electric charge on the object; chemical potential energy, with the chemical potential of a particular atomic or molecular configuration acting on the atomic/molecular structure of the chemical substance that constitutes the object; thermal potential energy with the electromagnetic force in conjunction with the temperature of the object.
For an example of gravitational potential energy, consider a book placed on top of a table.
To raise the book from the floor to the table, work must be done, and energy supplied. (If the book is lifted by a person then this is provided by the chemical energy obtained from that person's food and then stored in the chemicals of the body.) Assuming perfect efficiency (no energy losses), the energy supplied to lift the book is exactly the same as the increase in the book's gravitational potential energy.
The book's potential energy can be released by knocking it off the table.
As the book falls, its potential energy is converted to kinetic energy.
When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
Explanation:
Answer:
potential energy is basically stored energy
Explanation:
A photovoltaic cell produces electricity when the sun shines. What energy conversion is going here?
Answer:
light potential energy is converted into electrical potential energy.
Explanation:
A solar heat absorbs the light that creates pairs of electron - holes, these free charges when moving create a current, the light energy stored in the radiation is converted into electrical energy within the n-p junctions.
In summary, light potential energy is converted into electrical potential energy.
You get out of school and walk north for 20 minutes. You travel
1.6 km. What is your average velocity?
What is the
Answer:
[tex]\boxed {\boxed {\sf v= 0.08 \ km/min \ North}}[/tex]
Explanation:
Velocity is found by dividing the displacement by the time.
[tex]v=\frac{s}{t}[/tex]
where s is the displacement and t is the time.
The displacement is 1.6 kilometers, but it needs a direction as well. The question notes you walked North. The time is 20 minutes.
[tex]s= 1.6 \ km \ North \\t= 20 \ min[/tex]
[tex]v=\frac{1.6 \ km \ North} { 20 \ min}[/tex]
Divide.
[tex]v= 0.08 \ km/min \ North[/tex]
Velocity is a vector quantity, so that is why it has the measurement and the direction.
The average velocity is 0.08 kilometers per minute North.

One advantage that sexual reproduction has over asexual reproduction is the ability to produce genetic diversity. Why is genetic diversity an advantage?
Answer:
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population

6 A textbook sitting on a table weighs 3.6 N. If you push straight down on the book with a force of
84 N. what is the force acting on the book?
Force (N) = 250
Mass (kg) = 221
Acceleration (m/s^2) = ?
Answer:
The required acceleration is [tex]a=1.1[/tex] m/s²
Explanation:
Given
Force F = 250 NMass m = 221 kgTo determine
Acceleration a = ?
We know that acceleration is produced when a force is applied to a body.
The acceleration can be determined using the formula
[tex]F = ma[/tex]
where
F is the force m is the mass a is the accelerationnow substituting F = 250 , and m = 221 in the formula
[tex]F = ma[/tex]
[tex]250 = 221 (a)[/tex]
switch the equation
[tex]221(a) = 250[/tex]
Divide both sides by 221
[tex]\frac{221a}{221}=\frac{250}{221}[/tex]
simplify
[tex]a=\frac{250}{221}[/tex]
[tex]a=1.1[/tex] m/s²
Therefore, the required acceleration is [tex]a=1.1[/tex] m/s²

A tennis ball covers a distance of 12 meters in 0.4 seconds what is the velocity of the tennis ball?
Answer:
30m/s
Explanation:
Given parameters:
Distance = 12m
Time taken = 0.4s
Unknown:
Velocity of the tennis ball = ?
Solution:
Velocity of a body is the displacement per unit of time.
Velocity = [tex]\frac{displacement}{time}[/tex]
So;
Velocity = [tex]\frac{12}{0.4}[/tex] = 30m/s

1. A ball rolls off a 1.0 m high table and lands on the floor, 3.0 m away from the
table.
A. What is the vertical velocity of the ball just before it hits the floor?
d. What is the horizontal velocity of the ball just before it hits the floor
Answer:
5.55m/s
Explanation:
The vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
Which type of motion is projectile motion?
Projectile motion is an example of two dimensional motion.
Given is a ball rolls off a 1 m high table and lands on the floor 3 m away from the table.
Using the second equation of motion for the vertical motion -
S = ut + 1/2at²
S = 0 + 1/2at²
S = 1/2at²
t²= 2S/a
t² = (2 x 1)/9.8
t² = 2/9.8
t² = 0.2040
t = 0.451
Now, the vertical velocity of the ball just before it hits the floor -
v = u + at
v = 0 + at
v = at
v = 9.8 x 0.451
[v] = 4.42 m/s
Now, using the second equation of motion for horizontal direction -
S = ut + 1/2at²
S = ut + 0
3 = u x 0.451
u = 3/0.451
[u] = 6.6 m/s
Which is also the horizontal velocity of the ball just before it hits the floor.
Therefore, the vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
