Question

If the impulse is 12 newton . seconds and the force is 5 newtons, how long did the force act?

Answer 1

2.4s

Explanation:

Given parameters:

Impulse = 12Ns

Force = 5N

Unknown:

Time taken for the force to act = ?

Solution:

Impulse is the change in momentum of a body when an external force acts on  body for a period of time.

  Impulse = force x time

  Since the unknown in this problem is time, we make it the subject of the formula;

        Time = $\frac{impulse}{force}$

 

    Inputting the parameters;

 

         Time taken for force to act = $\frac{12}{5}$ = 2.4s
