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?

Solution Summary

This solution calculates the velocity and speed of a bullet.
