If the impulse acting on a system is known and the total time is also known, then we also know
A) the average force acting on the system.
B) the instantaneous force acting on the system.
C) the final momentum.
D) the initial momentum.

Quizplus · Accepted Answer

Impulse is defined as the change in momentum of an object when a force is applied over a period of time. It is also equal to the average force multiplied by the time interval over which the force is applied. Therefore, knowing the impulse and the total time allows us to calculate the average force acting on the system. Instantaneous force, final momentum, and initial momentum cannot be determined solely from the impulse and total time without additional information.
