- Since the free-falling acceleration is not dependent on mass, the final velocities of both masses are the same.
The kinetic energy = KE = mv2/2 - Hence, the kinetic energy of the heavier mass will be more.

Two masses m and 2m are dropped from certain height ‘h’. T...
When two objects of different masses are dropped from a certain height, they will fall towards the ground due to the force of gravity. The acceleration due to gravity, denoted as "g," is constant and is approximately 9.8 m/s^2 on Earth.
Since both masses are dropped from the same height, they will experience the same gravitational force. According to Newton's second law of motion, the force acting on an object is equal to the product of its mass and acceleration. Therefore, the force acting on the mass "m" is m * g, and the force acting on the mass "2m" is (2m) * g = 2mg.
As a result, the acceleration experienced by the mass "m" is given by the equation F = m * a, where "F" is the force and "a" is the acceleration. By substituting the force as mg, we get:
mg = m * a
Simplifying the equation, we find:
g = a
This means that both masses will have the same acceleration, regardless of their individual masses.
Therefore, both masses will fall towards the ground with the same acceleration of approximately 9.8 m/s^2. However, the mass "2m" will experience twice the force as the mass "m" due to its greater mass.
