Two pendulum bobs A and B are hung side by side in contact with another at rest each supported by a thread of 2m long. A has a mass of 0.2Kg and B has a mass of 0.8Kg. Bob A is then pulled to one side with its thread tight until it o.1 m higher. Then it is released so that it collides with B. After collision B gain 0.5m of higher. Calculate (i) the speed of A before impact(ii) the speed of B just after impact(iii) the speed kf A after impact(iv) the height gained by A after impact(V) the loss of kinetic energy/ energy as result of the impact
