A 67.3 kg ice skater moving to the right with
a velocity of 2.52 m/s throws a 0.151 kg snowball to the right with a velocity of 33.7 m/s
relative to the ground.
What is the velocity of the ice skater after
throwing the snowball? Disregard the friction
between the skates and the ice.
Answer in units of m/s

A second skater initially at rest with a mass
of 61.4 kg catches the snowball.
What is the velocity of the second skater
after catching the snowball in a perfectly inelastic collision?
Answer in units of m/s
