A bike rider accelerates constantly to a velocity of 8.0 m/s during 4.2 s. The bike's displacement during the acceleration was 19 m. What was the initial velocity of the bike?

DrBob222,
x= 1/2(Vo + V)t
Solve for Vo
Post your work if you get stuck.

nada mohammed,
can u give the answer

Physics 
DrBob222,
x = 19 m
Vo = unknown
V = 8.0 m/s
t = 4.2 s
