Potential and Kinetic Energy

Question 15 • Fall 24 GSE Physical Science B IC

A sled is at rest at the top of a slope 2 m high. The sled has a mass of 45 kg. What is the sled’s potential energy? (Formula: PE = mgh)

Answer
A
90 J
B
56.8 J
C
441 J
D
882 J

Explanation

Use PE = mgh, with mass 45 kg, gravitational acceleration 9.8 m/s², and height 2 m. PE = 45 × 9.8 × 2 = 882 J, so the sled’s potential energy is 882 J (choice D).
