1:15 Translating the problem to physics
2:35 Why is it final speed and not velocity?
3:48 Solving for the acceleration
6:03 Converting initial velocity to meters per second
7:32 Solving for distance traveled.
8:05 A common mistake
10:02 Two more ways to solve for the distance traveled.
10:45 Why didn't the speedometer show the correct final speed?
