How to find Acceleration from Velocity Initial, Distance and Time

[From: ] [author: ] [Date: 11-09-30] [Hit: ]
a=0.or a=0.......
What equation(s) do I use? The original question is " A car initially at rest travels a distance of 30.0 m in 8.0 s with uniform acceleration. Determine the magnitude of the acceleration of the car (in m/s^2)"

Use the equation
s = ut + (1/2)at^2
Here u=0
t=8 sec
s=30 m

Putting the values,you will get

30 = 0 + (1/2)a(64)
30=32a
a=30/32
a=0.9375 m/s^2
or a=0.94 m/s^2 (approx)
