Question

A car accelerates uniformly in a straight line from 10 m/s to 20 m/s in 5 seconds.
What is the acceleration?

Answer 1

Answer:

acceleration= change in speed/time

a=20-10/5

a=10/5

a=2m/s^2

Answer 2

Answer:

acceleration = final velocity - initial velocity /time

= 20- 10 m/s /5s

= 10 m/s /5s

2m/s^2
