A 73.5 kg ice skater moving to the right with a velocity of 2.97 m/s throws a 0.21 kg snowball to the right with a velocity of 29.3 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.
m/s to the right
(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?
m/s to the right

1 answer

initial mass = 73.5 + .21

initial momentum = (73.5 + .21)(2.97)

final momentum is the same
= .21 (29.3) + 73.5 v

solve for v

solve the second part the same way
initial momentum = .21*29.3
= (.21+61.5)v
