An object travelling in a straight line accelerates from rest for 10 seconds at 4.0 m s-2. It then travels at constant velocity for 30 s before decelerating at 16 m s-2 and coming to rest. i) Sketch a velocity time graph for this motion. ii) Calculate the total distance travelled by the object during the motion described.
