Question

A sports car accelerates from rest to 26.8 m/s (roughlv 60 min) in 5.1 seconds. What le the acceleration the car

Answer 1

Given:

$v_i=0$

$v_f=\rm 26.8\: m/s$

$\Delta t=\rm 5.1\: s$

The acceleration the car

$$a=\frac{\Delta v}{\Delta t}\\ a=\rm\frac{26.8\: m/s-0\: m/s}{5.1\: s}=5.25\; m/s^2$$
