A bag of sand of mass M is suspended by a string. A bullet of mass m is fired at it with velocity v and gets embedded into it. The loss of kinetic energy in this process is

A bag of sand of mass m is suspended by a rope. A bullet of mass (m)/(20) is fired at it with a velocity vand gets embedded into it. The velocity of the bag finally is

A block of wood of mass 3M is suspended by a string of length (10)/(3) m . A bullet of mass M hits it with a certain velocity and gets embedded in it. The block and the bullet swing to one side till the string makes 120^@ with the initial position. the velocity of the bullet is (g=10 ms^(-2)) .

A block of wood of mass 9.8 kg is suspended by a string. A bullet of mass 200 gm strikes horizontally with a velocity of 100 ms^(-1) and gets embedded in it. The maximum height attained by the block is (g = 10 ms^(-2)) .

A bullet of mass m is fired with velocity v in a large bulk of mass M. The final velocity v' will be

A bullet of mass 10 gm strikes a target at 400 m//s velocity and does half of its initial velocity. The loss of kinetic energy in joules is
