An open rail road car of mass M is moving with initial velocity v_(0) along a straight horizontla and friction less track.It suddenly starts raining at time t=0. The rain drops fall vertically with velocity with velocity u and add a mass of m kg //sec of water . The velocity of car after t second is

An open topped rail road car of mass M has an initial velocity v_(0) along a straight horizontal frictionless track. It suddenly starts raising at timet = 0. The rain drops fall vertically with velocity u and add a mass m kg/sec of water. The velocity of car after t second will be (assuming that it is not completely filled with water)
