Question

Starting from rest, a race car moves 128 m in the 5.0 s of uniform acceleration. What is

the car's acceleration?

Answer 1

10.24 m/s^2

Step-by-step explanation:

You can start with the relation ...

d = (1/2)at^2

Solving for a, we have ...

a = 2d/t^2

a = 2(128 m)/(5 s)^2 = 10.24 m/s^2
