Two particles of masses m1 and m2 and velocities u1 and αu1 ( α≠0) make an elastic head on collision. If the initial kinetic energies of the two particles are equal and m1 comes to rest after collision, then A glass ball collides with a smooth horizontal surface (xz plane) with a velocity V=ai-bj. If [...]

Two masses 2m and m are connected by an inextensible light string. The string is passing over a light frictionless pulley. The mass 2m is resting on a surface and mass in is hanging in air as shown in Fig. A particle of mass in strikes the mass in from below in case (I) with a velocity v0 and in case (II) strikes mass in with a velocity v0 from top and sticks to it.
