Question

can energy be stored? a 0.2 kg disc is being held 1.6 meters above the ground. how much gravitational potential energy does the disc have? remember : $e_g = mgh$ $g = 10 \frac{m}{s^2}$ $e_g = ? j$

Explanation:

Step1: Identify given values

Mass \( m = 0.2 \, \text{kg} \), height \( h = 1.6 \, \text{m} \), \( g = 10 \, \frac{\text{m}}{\text{s}^2} \)

Step2: Apply gravitational potential energy formula

Use \( E_g = mgh \). Substitute values: \( E_g = 0.2 \times 10 \times 1.6 \)

Step3: Calculate the result

\( 0.2 \times 10 = 2 \), then \( 2 \times 1.6 = 3.2 \)

Answer:

\( 3.2 \)
