A football player has a mass of 65 kg and is moving with a velocity of 5 m/s. What is the player’s momentum?
Answer
A
13 kg • m/s
B
70 kg • m/s
C
305 kg • m/s
D
325 kg • m/s
Explanation
Momentum is mass multiplied by velocity: p = mv. Using 65 kg and 5 m/s gives p = 65 × 5 = 325 kg·m/s. Therefore, the player’s momentum is 325 kg·m/s, choice D.
