A bullet of mass m=50 gm strikes `(Deltat~~0)`a sand bag of mass M =5 kg hanging from a fixed point, with a horizontal velocity `vec(v)_(p)`. If bullet sticks to the sand bag then the ratio of final & initial kinetic energy of the bullet is

A bullet of mass m = 50 gm strikes a sand bag of mass M = 5 kg hanging from a fixed point, with a horizontal velocity vecv_(p) . If bullet sticks to the sand bag then the ratio of final & initial kinetic energy of the bullet is (approximately) :

A bullet of mass m=10 gm strikes a hanging block of mass M=50 gm inelastically, with a horizontal velocity v_(0)=60 m//s . Find the change in tension (in N) in the string during collision. Round of to nearest integer. (Take : l=1m)

A bullet of mass m moving with a horizontal velocity v entered a block of mass M. As a result , the block and the bullet start moving together. Show that, after the impact, m/(M+m) part of the kinetic energy of the bullet is available as mechanical energy. What happens to the rest of the energy?
