Two identical beads, each of m=100g , are connected by an inextensible massless string, which can slide along the two arms AC and BC of a rigid smooth wire frame in a vertical plane. If the system is released from rest, the kinetic energy of the first bead when the second bead has moved down by a distance of 0.1m is xxx10^-3J . Find the value of x(g=10ms^-2) (shown situation is after movement of 0.1m ).

In ancient time, deffernt system of units was following in which unit of mass was " ser ", unit of length was " gaj " & unit of time was " kall " 1ser=900 gm , 1gaj=90cm , 1 kaal=3hr . A ball of mass 9kg is moving with velocity 10 m//s . Then its momentum ( mv ) in ancient system will be :-

Three spheres, each of mass m , can slide freely on a frictionless, horizontal surface. Spheres A and B are attached to an inextensible, inelastic cord of length l and are at rest in the position shown where sphere B is struck by sphere C which is moving to the right with a velocity v_(0) . Knowing that the cord is taut where sphere B is struck by sphere C and assuming 'head on' inelastic impact between B and C , we cannot conserve kinetic energy of the entire system. The velocity of B immediately after collision is along unit vector

Two block A and B of masses m_(1) = 3kg and m_(2) = 6kg respectively are connected with each other by a spring of force constant k = 200 N//m as shown in figure. Blocks are pulled away from each other by x_(0) = 3cm and then released. When spring is in its natural length and block are moving towards each other, another block C of mass m = 3kg moving with velocity v_(0) = 0.4m//s (towards right) collides with A and gets stuck to it. Neglecting friction, calculate (a) velocity v_(1) and v_(2) of the blocks A and B respectively just before collision and their angular frequency . (b) velocity of centre of mass of the system, after collision, ( c) amplitude of oscillation of combined body, (d) loss of energy during collision.

In a new system of units, unit of mass is taken as 50 kg. unit of length as 100 m and unit of time is 1 minute. What will be the weight of a body in this system, if in SI sysem, its weight is 10 N?
