A rectangular block of mass M, with vertical faces, rolls on ahorizontal surface between two opposing jets. At t = 0, the blockis set into motion at speed Uo. Subsequently, it moves withoutfriction parallel to the jet axes with speed U(t). Neglect the massof any liquid adhering to the block compared with M. Obtain ageneral expression for the block acceleration a(t) and the blockspeed U(t).
