K.C.S.E Physics Q & A - MODEL 2011PP1QN15
​Figure 10 shows a simple pendulum of length 80cm. The pendulum bob whose mass is 50g oscillates between points A and B, through its rest position C. A and B are both 10cm higher than C
(a) (i) Indicate with an arrow, on the path ACB, the direction of the greatest velocity of the bob as it moves from A to B.
(ii) State the form of energy possessed by the pendulum bob at point A. (b) Determine: (i) the velocity of the bob at point C, (ii) the tension in the string as the bob passes point C.(take acceleration due to gravity g = 10 m/s2) (c) After some time, the pendulum comes to rest at point C. State what happens to the energy it initially possessed.
