variable mass 10 Month 12 Day 7 Hour 5 Min ago Karma: 6  
A cart of total mass M is at rest on a rough horizontal road. It ejects bullets at a rate of lambda kg/s at an angle theta with the horizontal and at a velocity u(constant) relative to the cart. The coefficeint of friction between the cart and the ground is mu. Find the velocity of the cart as a function of t. The cart moves with sliding.
