Question
1) A 1 kg moving at 1 m/s ha s a totally inelastic collision with a 0.7 kg mass. What is the speed of the resulting combined mass after the collision?
2) A 0.010n kg bullet is shot from a 0.500 kg gun at speed of 230 m/s. Find the speed of the gun.

1. conservation of momentum
1kg*1m/s=(1.7kg)V solve for v
2. initial momentum=0=.010(230)+.500V
solve for V. Notice is is negative.
1kg*1m/s=(1.7kg)V solve for v
2. initial momentum=0=.010(230)+.500V
solve for V. Notice is is negative.
