Momentum & Collisions (rifle bullet)

A rifle bullet with mass 8.00 g strikes and embeds itself in a block with mass 0.992 kg that rests on a friction-less horizontal surface and is attached to a coil spring. The impact compresses the spring 15.0 cm. Calibration of the spring shows that a force of 0.750 N is requires to compress the spring 0.250 cm.

1. Find the magnitude of the block's velocity just after impact.
2. What was the initial speed of the bullet?
