How much work is done on the skater by the wall

Reference no: EM13497386

An ice skater with mass of 50 kg pushes off from the wall of an ice rink. She begins at rest, and after letting go of the wall she is moving away from the wall with a speed of 3 m/s. Assume that the surface of the ice is approximately frictionless.
