Quizplus · Accepted Answer

The impulse delivered by a force is equal to the product of the force and the time for which it acts. In this case, the force is given as 2 N and it acts for a time interval of 2 ms = 0.002 s. Therefore, the impulse delivered by the force is given by:

Impulse = Force x time = 2 N x 0.002 s = 0.004 Ns = 4 mN s

Therefore, the best choice is C, which gives the impulse as 4.0 mN s.
