<h2>Olivia is on a Swing at Playground - Option 2 </h2>
Olivia is on a swing at the playground. Her kinetic energy increasing at x and her potential energy decreasing at x. At mean position velocity is maximum so kinetic energy ( K.E ) is also maximum and at mean position potential energy is minimum. Therefore, kinetic energy is increasing and potential energy decreasing at x.
The velocity of the wave is defined by the product of wavelength and frequency. The velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.
<h3>What is the velocity of the wave?</h3>
The velocity of the wave is defined by the product of wavelength and frequency. It is obtained from the formula of the wavelength which is given by;
Hence the velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.

Lumbar nerves transmit signals that allow us to walk. They are a pivotal part of the human body, and without them we would be immobile. Hope this helps.
I believe a broom is an example of a lever, so no, not a wedge.
Answer:
-1.46 m/s^2
Explanation:
Write down what is given first:
v0 = 12 m/s
vf = 0 m/s
d = 45 m
We are trying to find acceleration, so we will use the equation vf^2 = v0^2 + 2ad
Plug in the values we have:
0^2 = 12^2 + (2 x 45 x a)
a = - 1.46 m/s^2
Note that this acceleration is negative because the body is slowing down, so the acceleration with be negative, because the change in velocity is negative.
