Starting from rest, a bus leaves a
gas station with a constant
acceleration of 2 m/s^2 until it
reaches a speed of 10 m/s. The
bus then continues to move with
this speed (10 m/s) for 5 s. Then
the bus decelerates at 2.5 m/s^2
until it stops. What is the total
distance traveled by the bus?
(Answer: 95 m)
