Question

Whats the cats average acceleration from 12 to 24 seconds?

Answer 1

Taking any two points on the curve from 12 to 24 seconds.

Let, two points are P( 12, 8) and Q( 24, 0).

Now , acceleration is given by :

`a=(\Delta v)/(\Delta t)=\text{Slope of v-t curve}`

Now , slope

`m=(0-8)/(24-12)\\\\m=-(8)/(12)\\\\m=-(2)/(3)`

Therefore, average acceleration from 12 to 24 seconds is
`-(2)/(3)` .

Hence, this is the required solution.
