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

Answer:

The average acceleration is about 8.51 m/s

Explanation:

     We can use the formula for acceleration to solve.

a = $\frac{velocity_{final} -velocity_{start} }{time}$

a =  $\frac{80-0}{9.4}$

a =  $\frac{80}{9.4}$

a ≈ 8.51
