8. Which object has the greatest gravitational potential energy? a) 0.25 kg ball stuck in a tree 2 m above the ground b) 100 kg rock sitting on the earth c) 1 kg box resting on a shelf 5 m above the earth

## Step 1The gravitational potential energy of an object is given by the formula:### where is the mass of the object, is the acceleration due to gravity, and is the height of the object above the ground.## Step 2We need to calculate the gravitational potential energy for each of the given objects using the formula.## Step 3For the 0.25 kg ball stuck in a tree 2 m above the ground, the gravitational potential energy is calculated as:### ## Step 4For the 100 kg rock sitting on the earth, the gravitational potential energy is calculated as:### ## Step 5For the 1 kg box resting on a shelf 5 m above the earth, the gravitational potential energy is calculated as:### ## Step 6Comparing the gravitational potential energy of all three objects, the 1 kg box resting on a shelf 5 m above the earth has the greatest gravitational potential energy.
