A motorcycle traveling at 25 m/s accelerated at a rate of 7.0 m/s2 for 6.0 seconds. What is the final velocity of the motorcycle?

First write down all your known variables:

vi = 25m/s

a = 7.0m/s^2

t = 6.0s

vf = ?

Then choose the kinematic equation that relates all the variables and solve for the unknown variable:

vf = vi + at

vf = (25) + (7.0) (6.0)

vf = 67m/s

The final velocity of the motorcycle is 67m/s.
