Acceleration

[Lacrosse22]

A certain roller coaster accelerates its cars 6.35 m/sec(s2) up the first incline. If this acceleration happens during the first 7.0 s of the ride, how much does the speed of the roller coaster cars increase?

I divided 6.35 m/s2 by 7.0 s and got my answer of 0.91 m/s. I'm not to sure how to approach this problem.

Use Galileo's first equation"

\(\displaystyle V \ = \ U \ + \ a * t\)

where V = final velocity

U = initial velocity

a = acceleration

t = time elapsed
