Question

1.

If a force of 40N is applied for 0.2 sec

to change the momentum of a

volleyball, what is the impulse?

Answer 1

J = 8 kg-s

Step-by-step explanation:

Given that,

Force, F = 40 N

Time, t = 0.2 s

We need to find the impulse. We know that,

Impulse, J = F×t

So,

J = 40 × 0.2

J = 8 kg-s

So, the impulse is 8 kg-s.
