Name: Date: Pd: Question 4 A car is traveling at a constant Speed S. in the negative direction. We begin paying attention at t = 0 seconds and observe the car travel at that constant speed for I second. Between t = 1's and t = 2 s the driver slams on the brakes and applies a strong constant braking force. Beginning at t = 2 seconds, the driver slowly eases off of the brake pedal until t = 3 seconds, at which point the driver foot is completely off the brake pedal. The speed of the car is = S a 35, att = 1 second. Sketch a graph of the car's velocity and acceleration over a 4-second interval. The car never comes to a stop. 1 0+ 4 . t (s 3 So velocity So -So amax acceleration 0 t (s) 2 amax
