Linear Momentum
Consider two unequal masses, M and m. Which of the following statements is false?
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?
A very heavy object moving with velocity v collides head-on with a very light object moving with velocity -v. 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?
A red ball with a velocity of +3.0 m/s collides head-on with a yellow ball of equal mass moving with a velocity of -2.0 m/s. What is the velocity of the yellow ball after the collision?
A 3.0-kg object moves to the right at 4.0 m/s. It collides in a perfectly inelastic collision with a 6.0 kg object moving to the left at 2.0 m/s. What is the total kinetic energy after the collision?
