1. The problem statement, all variables and given/known data Question: In pairs figure skating, the heavy muscular male and the petite female skater skate towards each other and come to a stop when the female is lifted. Who undergoes a bigger momentum change? a. the heavier skater b. the lighter skater c. same momentum change d. we must know the exact masses and velocities to answer this question Second part of the question: Continuing from the previous question, the heavy male skater proceeds to toss the lighter female skater, what happens to the male skater? a. he moves back just as fast as the lighter skater b. he does not move at all c. he starts spinning d. he moves back but at a lower speed than the lighter skater 2. Relevant equations moment = mass x velocity 3. The attempt at a solution First part of the question: This is a question my friend posted on Snapchat and it got me wondering. His answer is (c (same momentum change)), but I think the answer should me (d). Here is my explanation: since "momentum = mass x velocity", if the petite female skater is going at a higher speed than the heavy muscular male, it is possible that they might have the same momentum change, which is why we must know the exact masses and velocities to answer this question. Is my explanation correct? Which is the correct answer? Second part of the question: My answer for this one would be (d). Here is my explanation: Since momentum is conserved, and momentum is defined as "mass x velocity", and the female skater is lighter, the heavier skater needs to be at a lower speed in order to be equal to the momentum of the female skater. Is my answer and explanation correct for this question?
