It starts from rest meaning the initial velocity is 0
is accelerates at 5.7m/s^2 meaning a = 5.7m/s^2
t = 7.2s
vf = vi + at
vf = final velocity
vi = initial velocity
a = acceleration
t = time
we are looking for the final velocity
vf = vi + at
vf = 0 + (5.7 * 7.2)
vf = 41.04 m/s -------This is your answer
