A60 (a) A car of mass 1000 kg is initially at rest. It moves along a straight road for 20s and then comes to rest again. The speed-time graph for the movement is: vims 20 10 10 15 20 bs (i) What is the total distance travelled? (ii) What resultant force acts on the car during the part of the motion represented by CD? (iii) What is the momentum of the car when it has reached its maximum speed? Use this momentum value to find the constant resultant acceler- ating force.
