Academics

You have an inertia of 52 kg and are standing at rest on an iced-over pond in your skates. Suddenly, your 60-kg brother skates in from the right with x component of velocity -4.8 m/s and collides elastically with you.

What is the siblings' relative speed after the collision? Express your answer with the appropriate units.

If your brother's final x component of velocity is -0.34 m/s , what is your final velocity?

What is the change in kinetic energy of the system of you and your brother? Express your answer with the appropriate units.
