If the potential energy is 1962000 what is the kinetic energy of a boulder weighing 200 kg

To calculate the kinetic energy of the boulder, we need to know its velocity. The kinetic energy formula is given by:

Kinetic Energy = (1/2) * mass * velocity^2

Since we don't have the velocity information, we cannot directly calculate the kinetic energy. However, we can use the concept of conservation of energy to find the missing velocity.

The total mechanical energy in a system is conserved, meaning the sum of potential energy and kinetic energy remains constant. In this case, since we have the potential energy, we can equate it to the sum of the kinetic energy and potential energy at any point.

Potential Energy + Kinetic Energy = Total Mechanical Energy (constant)

So, we have:

Potential Energy + Kinetic Energy = Total Mechanical Energy
1962000 + Kinetic Energy = Total Mechanical Energy

Since the total mechanical energy is constant, the kinetic energy is the difference between the total mechanical energy and the potential energy:

Kinetic Energy = Total Mechanical Energy - Potential Energy

Without knowing the total mechanical energy, we cannot directly calculate the kinetic energy.
