To drive in a spy movie, Carson must do the following perfectly.Start from rest and increase speed with an acceleration of 8.0m/s^2 for 3.0 s. He must then coast (keep same speed) for 1.0 s,and then apply the brakes to stop with a constant acceleration in20.0 m. Once stopped, he must take virtually no time and put it inreverse to accelerate backward until he is 30.0 m in front of wherehe started the scene and traveling backward at 16.0 m/s. [OK, onehint.

a. How much time did this all take?
b. What is Carson's displacement when backing up?
