A car starts from rest and travels for 5.0s with a uniform acceleration of 1.5m/s^2. The driver then applies the brakes, causing a uniform negative accelreeation of -2.0m/s^2. If the brakes are applied for 3.0s, how fast is the car going at the end of the braking period, and how far has it gone?

Answer in back of the book: 1.50m/s, 32.3m
