Question

a 6.8 kg painting is hanging 3 meters above the ground. how much gravitational potential energy does the painting have? remember : $e_g = mgh$ $g = 10 \frac{m}{s^2}$ $e_g = ? j$

Explanation:

Step1: Identify given values

Mass \( m = 6.8 \, \text{kg} \), height \( h = 3 \, \text{m} \), gravity \( g = 10 \, \frac{\text{m}}{\text{s}^2} \)

Step2: Apply gravitational potential energy formula

\( E_g = mgh \)
Substitute values: \( E_g = 6.8 \times 10 \times 3 \)

Step3: Calculate the result

\( 6.8 \times 10 = 68 \), \( 68 \times 3 = 204 \)

Answer:

204
