A ride-sharing car moving along a straight section of road starts from rest, accelerating at 2.00 m/s" until it reaches a speed of 35.0 m/s. Then the vehicle moves for 47.0 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 ride-sharing car in motion (in s)? (b) What is the average velocity of the ride-sharing car for the motion described? (Enter the magnitude in m/s.) m/s
