Question 18
H60%

Two balls are dropped from the same height above the ground. Ball R has a mass of 0.10 kg and ball S has a mass of 0.40 kg. Air resistance is negligible. Which statement about the balls just before they reach the ground is correct?

[1]
A

ball S is faster because it has the larger gravitational potential energy store

B

ball R is faster because it has the smaller gravitational potential energy store

C

ball S is faster because its kinetic energy store gains more energy as it falls

D

both balls have the same speed because mass appears in both energy equations
