Bullet of mass embeds itself in a

wooden block with mass which then compresses a spring by a distance

before coming to rest. the coefficient of kinetic friction

between the block and table is (a) what is the

initial velocity (assumed horizontal) of the bullet? (b) what

fraction of the bullet’s initial kinetic energy is dissipated

(in damage to the wooden block, rising temperature, etc.)

in the collision between the bullet and the block?
