Question

A 60-kg skater, initially stationary, throws a 4.0-kg medicine ball (also initially stationary) horizontally to the left. Suppose the ball is pushed thru a 0.50 m displacement before leaving the skater's hand at a speed of 7.0 m/s , relative to the ice. Assume the surface under the skater to be frictionless, and ignore air resistance. Use a rightward-positive x-axis, and an upward-positive z-axis.

Part B

Determine the skater's displacement during the throw.

Part C

Determine the skater's horizontal velocity after the throw.
