Question

A car accelerates uniformly from rest and reaches 30.0 km/h in 10.0 s. What is

the acceleration of the car?

Answer 1

0.833 m/s^2

Step-by-step explanation:

First convert this:

30 km/h to m/s = 8.33 m/s

so now you have this:

Vi= 0 m/s

Vf= 8.33m/s

Δt= 10s

a = ?

Best formula is this:

Vf = Vi + aΔt

So:

8.33 = 0 + a(10)

= 0.833 m/s^2

This is give or take because of possible rounding issue.

I hope this helps!
