The builders of the pyramids used a long ramp to lift 20000-kg (20-ton) blocks. What is the gravitational potential energy of one of the blocks if it’s now 79 m above the ground?
GPE= mass*g*79m
To calculate the gravitational potential energy of an object, we will use the formula:
Gravitational Potential Energy = mass × gravitational acceleration × height
Given:
Mass of the block = 20,000 kg
Height = 79 m
We also need to know the value of gravitational acceleration, which is approximately 9.8 m/s^2.
Now, let's substitute the values into the formula:
Gravitational Potential Energy = 20,000 kg × 9.8 m/s^2 × 79 m
Calculating this equation will give us the answer.
To find the gravitational potential energy of the block, we can use the formula:
Potential Energy = mass * gravity * height
where:
- mass is the mass of the block (20,000 kg)
- gravity is the acceleration due to gravity (9.8 m/s^2)
- height is the height above the ground (79 m)
Let's plug in the values into the formula:
Potential Energy = 20,000 kg * 9.8 m/s^2 * 79 m
To get the answer, let me calculate it for you.
