Question

The velocity of a car traveling in a straight line increases from 0 meters/second to 30meters/second in 8 seconds. What is the average acceleration of the car?

Answer 1

The equation you need to know in order to solve this problem is v=v0+at, where v is final velocity, v0 is initial velocity, a is acceleration, and t is time.  Plug in and solve:

30=0+a(8)

30=8a

*Divide both sides by 8*

a=3/75m/s^2

Hope this helps!!
