There are numerous moons around the planet Saturn. During the formation of our solar system, these astronomical bodies would have interacted and possibly collided with each other. Imagine that one moon of mass m1 and circular orbital radius r1 originally had a velocity v1 until it collided with another moon of mass m2. This collision caused moon m1 to move in a new circular orbit with velocity 1.25v1. What is the new radius of m1 moon’s orbit?

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.
