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

$a=\frac{dv}{dt}$

replacing:

$\begin{gathered} a=\frac{60-0}{8-0} \\ a=\frac{60}{8} \\ a=7.5 \end{gathered}$

Therefore, the answer is 7.5 m/s^2
