Question: 12. How much impulse is needed to stop a 32-g mass traveling at a velocity of 38 m/s'? 42. 43. A force with a magnitude

12. How much impulse is needed to stop a 32-g mass traveling at a velocity of 38 m/s'? 42. 43. A force with a magnitude of 452 N is used to stop an object with a mass of 56.0 kg moving at a velocity of 155 m/s. How long will it take to bring the object to a full stop? 43. 44. A ball with a mass of 12 g is moving at 15 m/s. It collides with a second ball with a mass of 36 g moving at 5 m/s in the same direction. After the collision, the 12-g ball moves at 6.0 m/s. How great is the change in momentum of the 36-g ball
