Question

A race car goes forward from 0 to a velocity of 80 m/s in 9.4 s. What is its acceleration?

Answer 1

The average acceleration is about 8.51 m/s

Step-by-step explanation:

We can use the formula for acceleration to solve.

a =
`(velocity_(final) -velocity_(start) )/(time)`

a =
`(80-0)/(9.4)`

a =
`(80)/(9.4)`

a ≈ 8.51
