A bullet of mass A and velocity B is fired into a wooden block of mass C. If the bullet geta embedded in the wooden block.then velocity of wooden block after collision

A body of mass a moving with a velocity b strikes a body of mass c and gets embedded into it. The velocity of the systems after collision is

A bullet of mass m moving with velocity v strikes a block of mass M at rest and gets embedded into it. The kinetic energy of the composite block will be

A bullet of mass m moving horizontally with a velocity v strikes a block of wood of mass M and gets embedded in the block. The block is suspended from the ceiling by a massless string. The height to which block rises is

A bullet of mass 5gm is fired horizontally into block of mass 1kg at rest on a horizontal surface and gets embedded in it. The combination moves 5m before coming to rest. If mu_(k)=0.40 , what is the speed with which the bullet strikes the block ?

A block B is at rest on the rough horizontal surface as shown. Another block A collides with B . Then, which of the following statement is correct? ( i ) Impulsive friction acts on block B . ( ii ) Conservation of momentum can not be applied on a system (A+B) along x-"axis" for the situation just before and just after the collision. ( iii ) Conservation of momentum can be applied on system (A+B) along x-"axis" for the situation just before and just after the collision. ( iv ) Block A always moves along positive x-"axis" after collision.

A block A of mass m is give a velocity v_(0) towards another block B of sae mass B . Is attached to an ideal spring of spring constant K . A makes a head on perfectly inelastic collision with B . Answer the following two questions: Q. Let the collision takes place at time t=0 choose the instant (s), when the spring is in its natural length.
