A toy car is placed on the floor of a sports hall. It moves in a straight line from rest. It travels with constant acceleration for 4 seconds reaching a velocity of 5 m/s. It then slows down with constant deceleration of 1 m/s for 2 seconds. It then hits a wall and stops. (a)Draw a velocity graph for the car. (b)Work out the total distance travelled by the car. (c)An object with a mass of 75 kg moves with an acceleration of 12 m/s2, find the force exerted.
