Question

A race car accelerates from 0 m/s to 20.0 m/s with a displacement of 35.0 m. What is the vehicle's acceleration?

a 5.7 m/s2
b .84 m/s2
c 6.1 m/s2
d .29 m/s2

Answer 1

Step-by-step explanation:

Using Equations of Motion :

`{v}^(2) = {u}^(2) + 2as`

`a = \frac{{v}^(2) - {u}^(2)}{2s} = (400 - 0)/(70) = 5.71msec^( - 2)`
