A sled is at rest at the top of a slope 2 m high. The sled has a mass of 45 kilograms What is the sled’s potential energy? (Formula: cap p cap e is equal to mg h )

Use the potential energy formula, PE = mgh. Substituting the sled’s mass of 45 kg, gravity of 9.8 m/s², and height of 2 m gives PE = 45 × 9.8 × 2 = 882 J. The sled’s potential energy is 882 joules, choice D.
