Q- A solid cylinder, of radius c acted upon by no forces, moves parallel to its axis through a uniform cloud of fine dust, of volume density ρ, which is at rest. If the particles of dust which meet the cylinder adhere to it, and if m0 and u be the mass and the velocity at the beginning of the motion, find the distance x traversed in time t by the cylinder.
