Question

A force of 5 N is applied to an object for 10 seconds. What is the impulse?

Answer 1

The impulse is `50 Nxxs`

Explanation:

To answer this question we'll have to use the impulse equation:

• The force should have units of Newtons, N.
• The time should have units of Seconds, s.
• Impulse should have units of `Nxxs`

So we have the force and time, both of which have good units. All we have to do is multiply the two together to obtain the impulse:

`I = 5Nxx10s`

`I` = `50Nxxs`
