Question

If an object is moving at `3 m/s` and accelerates to `51 m/s` over 12 seconds, what was the object's rate of acceleration?

Answer 1

`4 m/s/s`

Explanation:

The rate of acceleration is the change in velocity over the change in time:
`a = (Delta v)/(Delta t) = (51 m/s - 3 m/s)/(12 s) = (48 m/s)/(12 s) = 4 m/s/s`
