Question

A constant force of 12 N acts for 5 s on a 5 kg object. What is the change in object's velocity?

Answer 1

`Deltav= 12m/s`

Explanation:

The impulse formulas

`I= mDeltav`
`I= FDeltat`

So:
`mDeltav= FDeltat`

Solving for the change in velocity or `Deltav`:
`Deltav= (FDeltat)/m`

`Deltav= (12N*5s)/(5kg)`

`Deltav= 12m/s`
