Question

The distance traveled by a marble on a flat table as it rolls in a straight line is determined by the formula:
S= ut + 1\2at^2,
where
s = Distance traveled u = Initial Velocity
t = Time elapsed
a = Acceleration
Which of the following shows the distance traveled formula solved for a?
A. a=2s-ut2/t^2
B. a=2s-ut/t^2
C. a=2s-2u/t
D. a= s-ut/t^2
