(i) the same speed as the medicine ball,
(ii) the same momentum as the medicine ball, or
(iii) the same kinetic energy as the medicine ball.
Rank these choices from the slowest to the fastest speed of the baseball.

1.(i), (ii), (iii)
2.(i), (iii), (ii)
3.(ii), (iii), (i)
4.(iii), (ii), (i)

Question 2

Object 1 has more kinetic energy than Object 2. How do the magnitudes of their momenta compare?
1. p1 = p2
2. p1 > p2
3. p1 p2
4. not enough information given to tell
