Flag In reaching her destination, a backpacker walks with an average velocity of 1.34 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.68 m/s, due west, urns around, and hikes with an average velocity of 0.447 m/s, due east. (a) How far east did she walk? (b) If she did not turn around and walked due east, how many hours would it take her to reach her destination with an average velocity of 1.34m/s due west?
Answer:
[tex]s_2=-806m[/tex]
Explanation:
From the question we are told that
Velocity 1 [tex]v=1.34m/s \angle west[/tex]
Distance [tex]d=6.44km=>6440m[/tex]
Velocity 2 [tex]v_3=2.68m/s[/tex]
Velocity 3 [tex]v_3=0.447m/s \angle east[/tex]
Generally the equation for VT is mathematically given by
[tex]VT=v_1t_1 +V_2t_2[/tex]
[tex]VT=2.68(2400)-0.447t_2[/tex]
[tex]1.34t_1+1.34t_2=2.68(2400)-0.447t_2[/tex]
[tex]t_2=1804s[/tex]
Therefore
[tex]s_2=v_2t_2=(-0.447)(1804)[/tex]
[tex]s_2=-806m[/tex]

A 55 kg skier is at the top of a slope. The vertical distance between start and finish is 10m. (a) What is her Potential Energy? (b) How fast is she moving at the bottom of the hill?
Explanation:
Given that,
Mass of a skier, m = 55 kg
The vertical distance between start and finish is 10 m.
(a) The potential energy of a skier is given by :
[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]
(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,
[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]
Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

Sugar dissolved in water is an example of?
A. Precipitate
B. Molecule
C. Compound
D. Solution
Answer:
D. Solution
Explanation:
Sugar dissolved in water is an example of solution.
A solution is a homogenous mixture of solutes and solvents.
In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.
The solvent is the water in this instance that helps to dissolve the solute.
Answer:
D. Solution
Explanation:
Dissolving sugar in water is an example of a physical change. Here's why:
A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result.
Explain What the core muscles do and why it's important to have a strong set of core muscles.
Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.
Explanation:
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.
