Question
A car starts from rest and moves with constant acceleration a = 2.0 m/s2 [Q3]
until it reaches v = 26.0 m/s speed. It then continues to move with this constant
speed. (a) For how long does the car accelerate? (b) How much distance is
covered by the car during the time it accelerates? (c) After reaching the speed
of v = 26.0 m/s, how much longer should the car travel until its average speed
?becomes v = 24.0m/s
