A self-driving car traveling along a straight section of road starts from rest, accelerating at 2.00 m/s until it reaches a speed of 40.0 m/s. Then the vehicle travels for 39.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the self-driving car in motion (In s)? (b) What is the average velocity of the self-driving car for the motion described? (Enter the magnitude in m/s.) m/s
