Application +4 | -1

A ball weighing 10 gm hits a hard surface vertically with a speed of 4m/s and rebounds with same speed. The ball remains contact with the surface for 0.01s. The average force exerted by the surface on the ball is

View answer and explanation

Correct option: D

8 N

Option D (8 N) is correct because the average force is calculated using the change in momentum divided by the time interval.
