a car starts from rest and travels 8.0s with a uniform acceleration of +2.0 m/s^2. the driver then applies the brakes, causing a uniform acceleration of -3.0 m/s^2. if the brakes are applied for 5.0s, determine each of the following.

a. how fast is the car going at the end of the braking period?
b. how far has the car gone?
