Energy to discover the skaters speed after gliding

Reference no: EM13674724

A 48 kg ice skater is gliding along the ice, heading due north at 5.0 m/s. The ice has a small coefficient of static friction, to prevent the skater from slipping sideways, however µk=0. abruptly, a wind from the northeast exerts a force of 4.0 N on the skater.

a) Use work and energy to discover the skater's speed after gliding 90 m in this wind. _________m/s
