What best describes an impulse acting on an object? a. the net force on an object divided by b. the time of impact the velocity of an object divided by its mass c. the product of an object's mass and the time of force impact d. the product of an object's mass and its change in velocity

d.the product of an object's mass and its change in velocity

Explanation:

The impulse is defined as the product between the net force F and the time of impact :

But we can rewrite the force as the product between mass and acceleration:

And the acceleration as the ratio between the change in velocity and the time of the collision:

Simplifying,

which corresponds to option d.
