A 150 g tenins ball coming at a speed of 40m/s is hit straight back by a bat to speed of 60m/s. The magnitude of the average force F on the ball, when it is in contact for 5ms is,

2500N

3000N

3500N

4000N

Text Solution

Verified by Experts

The correct Answer is:

Force F=Rate of change in the momentum
`=(m[v_(2)-v_(1)])/(t)`
`=((0.150kg)[60ms(-1)-(-40ms^(-1))])/((5xx10^(-3s))=3000N`.
