Question

The plot shows a simplified |F| versus time t plot during the collision of a 58 g Superball with a wall. The initial velocity of the ball is 29 m/s perpendicular to the wall; the ball rebounds directly back with approximately the same speed, also perpendicular to the wall. What is Fmax, the maximum magnitude of the force on the ball from the wall during the collision?

Answer 1

F = 3364 N

Step-by-step explanation:

This exercise can be worked with momentum momentum relationships

I = F t = ΔP = m
`v_(f)` -m v₀

With the ball bounces with the same speed, but with reversed direction

F t = 2 m v

F = 2 m v / t

F t = 2 58 10-3 29

F t = 3,364 N s

Time is taken from the graph of force against time, at the maximum point, if time is 1 s

F = 3364 N
