Question:

A 60-kg ice skater is standing on ice with ice skates (negligible friction). She is holding a flexible hose (essentially weightless) that directs a 2-cm-diameter stream of water horizontally parallel to her skates. The water velocity at the hose outlet is 10 m/s relative to the skater. If she is initially standing still, determine

(a) The velocity of the skater and the distance she travels in 5 s

(b) How long it will take to move 5 m and the velocity at that moment.
