A car moves on a straight line path, starting from rest at time 0. It undergoes a constant acceleration of 5 m/s for 5 seconds. Then the car experiences no acceleration for 10 seconds at which point it begins to accelerate steadily at -5 m/s' which it continues to do for the final 5 seconds of motion under study. Which graph of velocity vs. time correctly characterizes the motion of the car?
