Question

question 10 of 25 what is the potential energy of a 2 - kg book sitting on a shelf 2 meters above the ground? a. 39.2 j b. 2 j c. 4 j d. 19.6 j

Explanation:

Step1: Use gravitational potential energy formula

$PE = mgh$

Step2: Substitute values (m=2kg, g=9.8m/s², h=2m)

$PE = 2 \times 9.8 \times 2$

Step3: Calculate result

$PE = 39.2\ \text{J}$

Answer:

A. 39.2 J
