Q. Two bullets P and Q having mass 10kg and 40kg have velocitis of 20m/s and 5m/s. IF both strikes against a mud wall then
a) both pierce equally
b) P will pierce more
c) Q will pierce more
plz reply asap..

Both will pierce equally as both has same momenta equal to 200 kg m/s. Force is rate of change of momentum, that is change in momentum/sec. In this case both will apply same force so they will pierce equally. By the way, if you want to answer more questions like this then have a look at IIT-JEE, AIEEE 2011 Engineering Entrance Exams Preparation or consult me at Kajal Sengupta
