শক্তির নিত্যতা
When a small mass is suspended at the lower end of the elastic wire, with the upper end fixed to the ceiling. There is a loss in gravitational potential energy. let it be x, due to extension of wire. Mark correct option,
Work energy theorem
Since there is a loss so not recoverable half of it is lost rest is recoverable

A ball moving with a velocity v strikes a wall moving toward the ball with a velocity u. An elastic impact lasts for t sec. Then the mean elastic force acting on the ball is ;
A heavy ball moving with speed collides with a tiny ball. The collision is elastic, then immediately after the impact, the second ball will move with a speed approximately equal to-
A 50 gm ball collides with another ball of mass 150gm, moving in its direction of motion, After collision the two ;balls move at a an angle with their initial direction. Ratio of their velocities after collision is
A particle of mass , travelling at speed , strikes a stationary particle of mass . As a result, the particle of mass is deflected through and has a final speed of . Then the speed of the particle of mass after this collision is
