Your gym teacher throws a large and heavy medicine ball to you for you to catch. She is next going to throw to you a baseball that has a mass that is one tenth of that of the medicine ball. You are given the following choices. You can have the baseball thrown with

(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
