Answer:

9806.65 Joules

Explanation:

Lanuel

The block sitting on a platform contains 9,800 Joules of potential energy.

Given the following data:

  • Height = 20 meters
  • Mass of block = 50 kg

We know that acceleration due to gravity (a) for an object is equal to 9.8 meter per seconds square.

To find how much potential energy the block contains:

Mathematically, potential energy (P.E) is calculated by using the following formula:

[tex]P.E = mgh[/tex]

Where:

  • m is the mass of object.
  • g is the acceleration due to gravity.
  • h is the height of an object.

Substituting the given parameters into the formula, we have;

[tex]P.E = 50[/tex] × [tex]9.8[/tex] × [tex]20[/tex]

Potential energy = 9,800 Joules

Therefore, the block contains 9,800 Joules of potential energy.
