You want to enlarge a skating surface so you stand on the ice at one end and aim a hose horizontally to spray water on the schoolyard pavement. Water leves the hose at 3. 9 kg/s with a speed 19. 8 m/s. If your mass is 81 kg, what is your recoil acceleration? Neglect friction and the mass of the hose. Answer in units of m/s squared.
