(chatquestion)...Centre of Mass ALLEN CAREERINS RCISE a Class Asimple penduhmis suspended from a peg on a vertical wall. The pendulum spuled away from the wall to ahorizontal position (see fig.) and released. What is the The ball hits the well, the coefficient of restitution being V5 minimum number of collisions after which the amplitude of oscillations becomes loss than 60 degrees? Two messes A &B each of 5 kg are suspended by a light inextensible string passing over a smooth massiass pulley such that mass A rest on smooth table &Bisheid at the position showwn. Mass Bis now gently lifted up to the pulley andalowed to fall from rest. Determine up to what height will A rise for the Easuing motion. 1m 2m B. 1.25 0.5 kg are connected with each other as shown in Fig. and rest over a 10. Three idenical bals each cf mass m = Smoo horizontal table. At momentt = 0, ball Bis imparted a horizontal velocity v=9ms. Calculate velocity of Aust before it collides with ball C. 10...(9)
