Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

The velocity of the center of mass never changes a
collision. The final velocity is equal to the initial
velocity.
1. A 55 kg skater at rest on a frictionless rink throws a 3 kg ball, giving
the ball a velocity of 8 m/s. What is the velocity of the center of
mass?
2. A 55 kg skater is skating at 3 m/s to the right with a 3 kg ball in their
hands. The skater throws a 3 kg ball, giving the ball a velocity of 8
m/s. What is the velocity of the center of mass?
