Linear Momentum
A small object with momentum 5.0 kgm/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 4.0 kgm/s. What is the magnitude of the large object's momentum change?
When a light beach ball rolling with a speed of 6.0 m/s collides with a heavy exercise ball at rest, the beach ball's speed after the collision will be, approximately:
A very heavy object moving with speed v collides head-on with a very light object at rest. The collision is elastic, and there is no friction. The heavy object barely slows down. What is the speed of the light object after the collision?
When a cannon fires a cannonball, the cannon will recoil backward because the:
Two identical 1500-kg cars are moving perpendicular to each other. One moves with a speed of 25 m/s due north and the other moves at 15 m/s due east. What is the total momentum of the system?
