Two skaters collide and grab on to each other on frictionless ice. One of them, of mass 70.0 kg, is moving to the right at 2.0 m/s while the other, of mass 65.0 kg, is moving to the left at 2.5m/s. a) What is the velocity (magnitude and direction) of these skaters just after they collide? b) Find the total kinetic energy before and after collision

Two skaters collide and grab on to each other on frictionless ice. One of them, of mass 70.0 kg,
is moving to the right at 2.0 m/s while the other, of mass 65.0 kg, is moving to the left at 2.5m/s.

a) What is the velocity (magnitude and direction) of these skaters just after they collide?
b) Find the total kinetic energy before and after collision.

Completely Inelastic Collision
Two skaters collide and grab on to each other on frictionless ice. One of them, of mass 70.0 kg,
is moving to the right at 2.0 m/s while the other, of mass 65.0 kg, is moving to the left at 2.5
m/s. a) What is the velocity (magnitude and direction) of these skaters just after they collide?
b) Find the total kinetic energy before and after collision.
