A 65.0 kg ice skater moving to the right with a velocity of 2.47 m/s throws a 0.18 kg snowball to the right with a velocity of 24.3 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 62.00 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
Use conservation of momentum:
(65+0.18)*2.47 = .18*24.3 + 65*vf
where vf is final speed of the ice skater
b).Again, use conservation of momentum:
0.18*24.3 = (62+0.18)*vf
