------------------------------------------------ Calculate the impulse experienced by:

A. A 65.8-kg halfback encountering a force of 1025 N for 0.350 seconds.

B. A 0.168-kg tennis ball encountering a force of 126 N that changes its velocity by 61.8 m/s.

Answer :

Final answer:

The impulse on the halfback is 358.75 Ns and on the tennis ball is 10.38 Ns. Impulse is calculated by the formula I = FΔt (force times time interval) or mass times change in velocity.

Explanation:

The subject of this question is impulse, which in physics, is the product of force and time, represented by the formula I = FΔt.

A. For the 65.8-kg halfback, the impulse can be calculated by multiplying force (1025 N) and time (0.350 s). So, I = 1025 N * 0.350 s = 358.75 Ns.

B. For the 0.168-kg tennis ball, the impulse can be calculated by multiplying the ball’s mass and its change in velocity. So, I = 0.168 kg * 61.8 m/s = 10.38 Ns.
