1. A Body Aof 5kg is attached to the end of a light supension cord 2m long and is free to swing in a cirular path in a vertical plane . the body A is drawn aside and the suspension cord is held taut at an angle of 30 below the horizontal . a. determine the linear velocity of the weight when passing through the bottom position b. at the instant of reaching the bottom position, body A collides with body B of mass 10kg moving horizontally with a velocity of 2m/s in the same vertical plane as, but in the opposite sense to Body A. if after impact on body A rebounds to height of 0.3m above it bottom postion determine the velocity of B immediately after impact. c. calcualte the loss of energy at impact I must confess i have got no clue on how to tackle the problem, and as such i dont know where to start on, so please i would really appriciate any help and explanation offered to me . thanks in advance.
