A 68.0 kg ice skater moving to the right with a velocity of 2.93 m/s throws a 0.18 kg snowball to the right with a velocity of 26.0 m/s relative to the ground. A) what is the velocity of the ice skater after throwing the snowball? Disregard the friction between the skates and the ice . B) a second skater initially at rest with a mass of 61.00 kg catches the snowball. What is the velocity of the second skater after catching the snowball in a perfectly inelastic collision?
