A tennis ball covers a distance of 12 meters in 0.4 seconds what is the velocity of the tennis ball?

Answers

V=d/t
V=12/0.4
V=30 m/s

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

What is the

Answers

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.

Define potential energy (PE)

Answers

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

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

Answers

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.
