Question

collision problem involving a spring.

Answer 1

A rifle bullet with mass 8.00g strikes and embeds itself in a block with mass 0.992 kg that rests on a frictionless, 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 0.750N is required to compress the spring 0.250cm

Answer 2

i need help finding the magnitude of the block's velocity just after impact and the initial speed of the bullet.
