Physics help - I know that this qn may be easy but pls help!?

Homework Statement

A motorist was driving along a level road at a steady speed. He had to brake as quickly as possible to avoid a collision. The motorcycle decelerated uniformly at 7.0m/s2 and stopped in 2.0s.

a) At what speed was the car traveling before the breakes were applied?
b) How far did the car travel during braking?
c) If the driver took 7.0s between seeing the child and starting to brake, what was the total stopping distance of the car?

You will need to state some of the related equations. What equations have you learned related to kinematics that you think you can use in this problem?
