Question

A car accelerates from 0 to 75 km/hr in 8 s. What is the car’s acceleration?

Answer 1

Step 1: divide 75 by 8
Step 2: get the answer - 75/8 = 9.375
Step 3: label the answer - 9.375 km/hr
*optional step*: estimate or round the decimal - 9.375 is rounded to 9.4 km/hr

Answer 2

The acceleration formula is
`a=(v-v_0)/(t)`

Plug in the values we know.

`a=(75-0)/(8)`

`a=(75)/(8)`

`a=9.375`

The car's acceleration is 9.375
`(m)/(s^2)`
