Answer :
Answer:
The velocity of the second skater is -1.05 m/s
Explanation:
Here we use the principle of conservation of momentum which states that p_1 + p_2 = 0 or p_1 = -p_2. The formula for momentum is p = mv, which means that m_1*v_1 = -m_2*v_2. Rearranging this equation to find v_2, we get -m_1*v_1/m_2 = v_2 (dividing both sides by -m_2.)
Now plugging in the numbers we get -44*1.60/67 = -1.05 m/s, which intuitively makes sense, since it takes more force to change the speed of, or accelerate, a heavier object (or, in this case, person.)
