Answer :
Final answer:
The defensive corner-back, with a mass of 121 kg moving at a speed of 10 m/s, has greater momentum (1210 kg.m/s) than the offensive tackle with a mass of 195 kg moving at a speed of 5 m/s (975 kg.m/s). This is based on the formula for momentum which is mass times velocity.
Explanation:
To determine which player has a greater momentum, we must first understand that momentum is calculated by the product of an object's mass and its velocity (p=mv). Thus, we can calculate the momentum for both players:
- The offensive tackle's mass is 195 kg and velocity is 5 m/s, therefore the momentum = 195*5 = 975 kg.m/s.
- The defensive corner-back's mass is 121 kg and his velocity is 10 m/s, hence, the momentum = 121*10 = 1210 kg.m/s.
Hence, comparing the momentum of both, we can conclude that the defensive corner-back with a mass of 121 kg moving at a speed of 10 m/s has greater momentum than the offensive tackle with a mass of 195 kg moving at a speed of 5 m/s.
