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,

A

2500N

B

3000N

C

3500N

D

4000N

Text Solution

Verified by Experts

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

The following problems illustrate the effect of a time-dependent force of a large average magnitude which acts on a moving object only for a short duration. Such forces are called 'impulsive' forces. According to the impulse-momentum theorem, impulse delivered to a body is equal to the change of linear momentum of the body. A ball of mass 250 g is thrown with a speed of 30 m//s . The ball strikes a bat and it is hit straight back along the same line at a speed of 50 m//s . Variation of the interaction force, as long as the ball remains in contact with the bat, is as shown in Fig. Maximum force exerted by the bat on the ball is
