Starting from rest, a car accelerates at 3m/s2 until it reaches a constant speed of 15m/s. After traveling at 15m/s for 12s, the brakes are applied so that the car comes to a stop, taking 3 s to do so. (Please show formulas)
A. Prepare visual overview of the situation. Your overview must include a pictorial representation that defines the coordinate system, a motion diagram, and an annotated velocity vs. time graph.
B.What total distance did the car travel?
C. The magnitude of the braking force required to bring the car to a stop was 2000N . What is the mass of the car?
