how much potential energy does a 4500kg piano is suspended by a rope 30 meters above the ground

PE= m*g*h

To calculate the potential energy of the piano, we need to use the formula:

Potential Energy = Mass * Acceleration due to Gravity * Height

First, let's find the acceleration due to gravity, which is approximately 9.8 m/s².

Next, we can substitute the given values into the formula:

Mass = 4500 kg
Acceleration due to Gravity = 9.8 m/s²
Height = 30 meters

Potential Energy = 4500 kg * 9.8 m/s² * 30 meters

Now, let's perform the calculation:

Potential Energy = 1323000 Joules

Therefore, the potential energy of the 4500 kg piano suspended 30 meters above the ground is 1,323,000 Joules.
