26. Two students are standing next to each other on a level field. One of the students throws a table tennis ball forward toward a line 2.0 m away. At the same time, the second student throws a bowling ball in the same direction. Both balls take the same time to travel the 2.0 m.

Only the second student feels a noticeable backward push when she throws her ball.

Which of the following statements explains why only the second student feels a noticeable backward push?
  1. The bowling ball exerts a much larger reaction force.
  2. The bowling ball undergoes a much larger acceleration
  3. The bowling ball requires more force to overcome gravity.
  4. The bowling ball converts more inertia into kinetic energy

28. Two full 2 L bottles of water are placed on a table. Bottle 1 was just removed from a refrigerator; bottle 2 is at room temperature.

Which of the following statements describes the average molecular kinetic energy and the speed of the molecules in each bottle?
  1. Bottle 1 has the same average molecular kinetic energy as
    bottle 2, and the molecules have the same average speed in both bottles.
  2. Bottle 1 has a smaller average molecular kinetic energy than
    bottle 2, and the molecules have the same average speed in both bottles.
  3. Bottle 1 has a smaller average molecular kinetic energy than
    bottle 2, and the molecules have a slower average speed in bottle 1 than in bottle 2.
  4. Bottle 1 has a larger average molecular kinetic energy than
    bottle 2, and the molecules have a slower average speed in bottle 1 than in bottle 2.

29. A student swings a bat horizontally, making contact with a ball thrown to her. The ball leaves the bat, and the bat continues moving through the rest ofthe swing.

Which of the following statements describes the change in energy ecessary to do work on the ball?
  1. All the kinetic energy of the bat is converted to work.
  2. All the potential energy of the bat is converted to work.
  3. Some of the kinetic energy of the bat is converted to work.
  4. Some of the potential energy of the bat is converted to work.
