Answer: 13590 kgm/s
Explanation:
Given that:
Mass of football = 453 kg
Speed by which football moves = 30m/s. Momentum of the football = ?
Recall that momentum is a product of mass and speed of a moving object
Thus, Momentum = Mass x Speed
= 453kg x 30m/s
= 13590 kgm/s
Thus, the momentum of the football is 13590 kgm/s
