Final answer:
To find the velocities of the two people after the snowball is thrown, we can use the conservation of momentum.
Step-by-step explanation:
In this problem, we have two people involved. The first person throws a snowball forward, while the second person catches it. To find the velocities of the two people after the snowball is thrown, we can use the conservation of momentum.
Let's assume that the positive direction is the direction in which the snowball is thrown. The momentum before the snowball is thrown is given by:
m1u1 + m2u2 = m1v1 + m2v2
Using the given values, we can solve for v1 and v2.
