A wedge is placed on a smooth horizontal plain and a rat runs on its sloping side. The velocity of the wedge is `v=4ms^(-1)` towards the right. What should be the velocity of the rat with respect to the wedge `(u)`, so that the rat appears to ,move in the vertical direction to an observer stading on the ground?

A ball of mass m moving horizotally which velocity u hits a wedge of mass M . The wedge is situated on a smooth horizontal source. If after striking with wedge the ball starts moving in vertical direction and the wedge starts moving in horizotal plane. calculate a. the velocity of wedge V . b. the velocity (v) at which the ball moves in vertical direction. c. the impulse imparted by the ball on the wedge. d. the coefficient of restitution e=?
