l Fido LTE 9:23 PM session s.com Item 6 MasteringPhysics Item 6 A 60-kg ice skater moves across the ice at a constant speed of 2.0 m/s. She is caught by her 67-kg partner, and then the pair continues to glide together. He is at rest when he catches her, and immediately afterward they both coast. Part A What is their velocity just after the catch? Assume she moves in the positive a-direction before her partner catches her Express your answer with the appropriate units. ValueUnits Ux,f Submit Give Up Part B A skater follows the girl at a constant speed of 1.0 m/s. What is the magnitude of the girl's change in momentum in the reference frame of the skater? Express your answer with the :1 Value Units appropriate units. Submit Give Up Continue>

Explanation / Answer

Part A

Conserving momentum

60*2=(60+67)*v

We got

v=0.945 m/s

Part B

Change in momentum=60*1+(60*0.055)=63.3 kgm/s
