A car starts from rest and travels for 6.5 s with a uniform acceleration of +1.7 m/s2. The driver then applies the brakes, causing a uniform acceleration of −2.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (b) How far has the car gone?
