ques 13

Dear Student,

Please find below the solution to the asked query:

If the balls are released from h height, the velocity gained by both balls just before colliding the ground are,

u1=u2=2gh
Given that the first ball goes to  height h/4 after colliding and the second ball to a height h/16. So, the velocities with which those two bounce back are,

v1=2gh4=2gh2 and v2=2gh16=2gh4Therefore, the impulse on both the objects are,I1=P1=mu1-v1=m2gh+2gh2=3m2gh2 and I2=P2=mu2-v2=m2gh+2gh4=5m2gh4Therefore,I2=56I15I1=6I2
