Показать описание
Learn when to use the acceleration equation final velocity squared equals initial velocity squared plus two times acceleration times displacement (vf^2 = vi^2 + 2ax), how to pick it from the acceleration equations, how to rearrange it, and walk through the following example: A skater glides off a frozen pond into a patch of ground at a speed of 2.9 m/s. Here she is slowed at a constant rate of 3.00 m/s2. How fast is the skater moving after she has slid 0.38 m across the ground?

I want to prove the law from the beginning.. Why is the square of the final velocity = the square of the velocityPrimary + 2 × displacement
