Question

A car accelerates uniformly from rest to 23 m/s over a distance of 30 meters. What is the acceleration of the car?

Answer 1

a= 17.69 m/s^2

Step-by-step explanation:

Step one:

given data

A car accelerates uniformly from rest to 23 m/s

u= 0m/s

v= 23m/s

distance= 30m

Step two:

We know that

acceleration= velocity/time

also,

velocity= distance/time

23= 30/t

t= 30/23

t= 1.30 seconds

hence

acceleration= 23/1.30

accelaration= 17.69 m/s^2
