from (d) (sin 0 - u cos og Two identical balls A and B are released from the positions shown in figure. They collide elastically on horizontal position MN. The ratio of the heights attained by A and B after collision will be (neglect friction): TO 45° ( Vision N (a) 1:4 (b) 2:1 (c) 4:13 (d) 2:5 23. Two equal spheres A and B lie on a smooth horizontal circular groove at opposite ends of a diameter. At time t = 0, A is projected along the groove and it first impinges on B at time t = T, and again at time t= T . Ife is the coefficient of restitution, the ratio T/T, is b) (2+e) --------- onis ame (a) 2
