Question

A race car accelerated from rest to 60 m/s when it crossed the finish line 8 seconds later. What was the car's acceleration? A. 0.13 m/s2 B. 7.5 m/s2 C. 52 m/s2 D. 68 m/s2 oorooooooo +

Answer 1

We have the following:

We have that the acceleration equation is the following

`a=(dv)/(dt)`

replacing:

`\begin{gathered} a=(60-0)/(8-0) \\ a=(60)/(8) \\ a=7.5 \end{gathered}`

Therefore, the answer is 7.5 m/s^2
