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

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