Answer Qb

67 (e) What do you understand by tdhe principle of conServation of energy? (b) Expiain how the principle applies to: (1) an object falling from rest in vacuo, (ii) a man sliding from rest down a. vertical pole, if there is a constant resistive force opposing the motion. Sketch graphs, using one set of axes for (i) and another set for (i), showing how each form of energy you consider varies with time, and point out the important features of the graphs. (c) A motor car of mass 600 kg moves with constant speed up an inclined straight road which rises 1.0m for every 40m travelled along the road. When the brakes are applied with the power cut off, there is a constant resistive force and the car
