Momentum
Problem: 8.C.3
Two balls are moving in the same direction. Ball A has half the mass of ball B, and is moving at twice its speed. (a) Which ball has the greater momentum? (b) Which ball has greater kinetic energy?
 (a)  (b) Problem: 8.1.2
A sport utility vehicle is travelling at a speed of v m/s. If its momentum has a magnitude of 32,800 kg·m/s, what is the SUV’s mass?
  kg Problem: 8.1.4
At a circus animal training facility, a monkey rides a miniature motorscooter at a speed of 7.0 m/s. The monkey and scooter together have a mass of m kg. Meanwhile, a chimpanzee on roller skates with a total mass of 44 kg moves at a speed of 1.5 meters per second. The magnitude of the momentum of the monkey plus scooter is how many times the magnitude of the momentum of the chimpanzee plus skates?
  Problem: 8.2.1
A golden retriever is sitting in a park when it sees a squirrel. The dog starts running, exerting a constant horizontal force of 89 N against the ground for 3.2 seconds. What is the magnitude of the dog’s change in momentum?
  kg·m/s Problem: 8.3.2
A cue stick applies an average force of 66 N to a stationary 0.17 kg cue ball for 0.0012 s. What is the magnitude of the impulse on the cue ball?

Problem: 8.3.4
A steel ball with mass 0.347 kg falls onto a hard floor and bounces. Its speed just before hitting the floor is 23.6 m/s and its speed just after bouncing is 12.7 m/s. (a) What is the magnitude of the impulse of the ball? (b) If the ball is in contact with the floor for 0.0139 s, what is the magnitude of the average force exerted on the ball by the floor?
 (a) kg·m/s  (b) N Problem: 8.6.2
A 332 kg mako shark is moving in the positive direction at a constant velocity of 2.30 m/s along the bottom of a sea when it encounters a lost 19.5 kg scuba tank. Thinking the tank is a meal, it has lunch. Assuming momentum is conserved in the collision, what is the velocity of the shark immediately after it swallows the tank?
