Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

3 Problem
At the "before" instant shown below, a soccer ball of mass m is rolling horizontally to the left
with speed v₁. A soccer player then kicks the ball as shown in the "after" instant, such that it
leaves her foot with speed v2 making an angle with the horizontal. The ball just clears her
opponent's head (at height h) when it reaches the apex of its projectile trajectory. Assume no
drag during the projectile motion. The gravitaitonal acceleration is g.
Question: If the soccer player foot makes contact with the ball for T seconds, what is the mag-
nitude of the average force vector Favg that her foot exerts on the ball? Write your answer as an
