A bullet with a mass of 0.010 kg is fired and has a velocity of 50 m/s. It strikes a block of wood whose mass is 2.0 kilograms which sits motionless on a horizontal frictionless table. (a) Find the velocity of the block if the bullet passes through it and emerges with a velocity of 10 m/s. (b) How much mechanical energy has been dissipated?
