Reference no: EM13331218

A thin block of soft wood with a mass of 0.074 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 641 m/s at a block of wood and passes completely through it. The speed of the block is 17 m/s immediately after the bullet exits the block.

(a) Determine the speed of the bullet as it exits the block.

(b) Calculate the initial and final kinetic energies of the system.
