Hi, I hope this finds you well. I am trying to solve this question. A cart with frictionless wheels holds a water tank, motor, pump, and nozzle. The cart is on horizontal ground and initially still. At time zero the cart has a mass M0 and the pump is started to produce a jet of water with area Aj , velocity Ujet at 30◦ to the horizontal. Find and solve the equations governing the mass and velocity of the cart as a function of time. The https://1drv.ms/i/s!AoYEdNE99fwNg-p8gsE0jzh1zbmdog [Broken] shows my solution. But this is not correct. Can anyone help me.
