A 3-kg steel ball strikes a wall with a ...

A 3-kg steel ball strikes a wall with a speed of `10.0ms^(-1)` at an angle of `60.0^(@)` with the surfaces of the wall. The ball bounces off with the same speed and same angle. If the ball was in contact with the wall for 0.2s, find the average force exerted by the wall on the ball.

Text Solution

Verified by Experts

Impulse, `I=2 mu cos 30^(@)`
`=2 xx 3 xx 10 xx (sqrt(3))/(2) = 30sqrt(3)Ns`
`F_(av)=(I)/(Delta t)=(30sqrt(3))/(0.2)=150 sqrt(3)N`.
