An object starts from rest and is uniformly accelerated so that its speed is 20 m/s after 20s. If it travels with this speed for 60 s and is then brought to rest by a uniform retardation in 10 s. Sketch the velocity-time graph and calculate the acceleration, the retardation and the total distance travelled.
