Question

A 10.0-g bullet is fired into, and embeds itself in, a 1.95-kg block attached to a spring with a force constant of 20.0 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block.

Answer 1

for collision. Po (0.010) (300) + (1.9500) = (1.95 +0.010) da 1.53 mis Using energy conservation, I mu k an? (1195+ 0.010) (1.592) = (20Nlm sx² | sx = 0.48m
