A freight car is moving on smooth horizontal track without any external force. Rain is falling at the rate of u m/s at an angle θ with the vertical. Rain drops are collected in the car at the rate of μ kg/s. If initial mass of the car is m0 and velocity v0 then find its velocity after time it.
v=2ucosθ(m0m0+μt−1)+m0v0(m0+μt)
v=usinθ(m0m0+μt−1)+3m0v0(m0+μt)
v=usinθ(m0m0+μt−1)+m0v0(m0+μt)
