Question 21 • FL-2003310-Physical Science

A 40 kg dog is sitting on top of a hillside and has a potential energy of 1,568 J. What is the height of the hillside? (Formula: PE = mgh)

Answer
A
3.9 m
B
4.0 m
C
39.2 m
D
40.0 m

Explanation

Rearrange PE = mgh to find height: h = PE ÷ (mg). Using the values given, h = 1,568 J ÷ (40 kg × 9.8 m/s²) = 1,568 ÷ 392 = 4.0 m, so the hillside is 4.0 m high.
