Agent 009 devised the following method of measuring the muzzle velocity of a rifle (Figure below). He fires a bullet into a 4.648-kg wooden block resting on a smooth surface, and attached to a spring of spring constant k = 142.7 N/m. The bullet, whose mass is 7.870 g, remans embedded in the wooden block. He measures the maximum distance that block compresses the spring to be 9.460 cm. (a) What is the speed of the bullet? (b) What is the loss in the kinetic energy of the bullet? (c) What is the spring force exerted on the block?

A 5.00-g bullet moving with an initial speed of v = 400 m/s is fired into and passes through a 1.00-kg block as shown in Figure P8.57. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 900 N/m. The block moves d = 5.00 cm to the right after impact before being brought to rest by the spring. Find (a) the speed at which the bullet emerges from the block and (b) the amount of initial kinetic energy of the bullet that is converted into internal energy in the bullet-block system during the collision.
