A light and a heavy object have the same momentum. Find out the ratio of their kinetic energies. Which one has a larger kinetic energy ?

Text Solution

AI Generated Solution

To solve the problem of finding the ratio of kinetic energies of a light object and a heavy object that have the same momentum, we can follow these steps: ### Step 1: Define the Variables Let: - Mass of the light object = \( m \) - Mass of the heavy object = \( M \) (where \( M > m \)) - Momentum of both objects = \( P \) ...
