Question

1. An average force of 200 N is applied over 10 seconds. What is the impulse?

Answer 1

Given data:

The average force is F=200 N.

The time taken is t=10 s.

The formula to calculate the impulse is given by,

$I=Ft$

Substitute the given values in above equation,

$\begin{gathered} I=(200N)(10s) \\ I=2000\text{ N}\cdot\text{s} \end{gathered}$

Thus, the magnitude of impulse is 2000 N·s.
