1 D Kinematics with non-constant acceleration 7. A car is driving towards a red light (at x0 = 0 and t0 = 0) with an initial speed of Vo. The acceleration of the car is a = {0 t < t1 −B(t−t1) t1 < t < t2, where the car's velocity is in the positive direction, B is a constant, and the car comes to a halt at time t2. a. What are the units of B? b. Without explicit calculation, first sketch the position, velocity, and acceleration vs. time graphs. c. Now calculate the velocity and position of the car as functions of time. Compare to your sketches. d. Determine t2, the time when the car stops. Answer: If t1 = 0.5 s, Vo = 18 m/s, and B = 16 (units?), you should calculate t2 = 2 s.
