A 15g bullet traveling at 300m/s strikes and is absorbed by a 75g object . find the speed with which the object moves off
conserve momentum
0.015*300 = (0.075+0.015)v
find v
shortway: 6 times the mass, so 1/6 the speed = 50 m/s
0.015*300 = (0.075+0.015)v
find v
shortway: 6 times the mass, so 1/6 the speed = 50 m/s
