355286 A particle is moving with velocity \(u=2 {~m} / {s}\) towards a heavy wall moving towards the particle with constant speed \(v_{0}=1 {~m} / {s}\) as shown in the figure. Assuming collision to be elastic, find the velocity of the particle immediately after the collision.

355287 A particle of mass ' \({m}\) ' is moving horizontally \({w i}\) th a speed ' \({v}\) ' towards a rigid wall which is moving in the opposite direction with a constant velocity \({u}\). Assuming elastic impact between the wall and the particle, the work done by the wall in reflecting the particle is :
