2] When an object falls freely towards the ground, its potential energy decreases, and kinetic energy increases; as the object touches the ground, all its potential energy becomes kinetic energy. As the object hits the hard ground, all its kinetic energy becomes heat energy and sound energy.06-
Step-by-step explanation:
Given :
- A man drops a 10 kg rock from the top of a 5 m ladder.
To Find :
- Kinetic energy of rock when it reaches the ground
Theory :
- • Work energy theorem
The change in kinetic energy of a particle is equal to the work done by the net force.
- • Law of conservation of mechanical energy
The sum of the potential energy and kinetic energy is called the total mechanical energy.
Solution:
We have to find Kinetic energy of rock when it reaches the ground.
By Work energy theorem
Put the given values
