A car starts from rest and travels for 10.0 s with a uniform acceleration of +2.0 m/s?. The driver then applies the brakes, causing a uniform acceleration of -1.5 m/s. If the brakes are applied for 1.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? m/s (b) How far has the car gone?
