People getting hit in their balls compilation

When a soccer ball is kicked toward a player and the player deflects the ball by "heading" it, the acceleration of the head during the collision can be significant. Figure 2-38 gives the measured acccleration a(t) of a soccer player's head for a bare head and a helmeted head, starting from rest. The scaling on the vertical axis is set by as=200  m / s^2. At time t=7,0  ms, what is the difference in the speed acquired by the bare head and the speed acquired by the helmeted head? | Numerade
