A car starts from rest at the point A and moves in a straight line with constant acceleration for 20 seconds until it reaches the point B. The speed of the car at B is 30 m s. Calculate (a) the acceleration of the car, (b) the speed of the car as it passes the point C, where C is between A and B and AC = 40 m. (OCR)
