A 74.0 kg ice skater moving to the right with a velocity of 2.90 m/s throws a 0.15 kg snowball to the right with a velocity of 23.2 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 61.50 kg catches the snowball. What is the velocity of the second skater after catching the snowball in a perfectly inelastic collision?

(PLEASE HELP!)
