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 sleds potential energy? (formula: pe = mgh) 90 j 56.8 j 441 j 882 j physical science a 2025 - 2026
Answer
Explanation:
Step1: Identify values
$m = 45\ kg$, $g= 9.8\ m/s^{2}$, $h = 2\ m$
Step2: Apply potential - energy formula
$PE=mgh=45\times9.8\times2$ $PE = 882\ J$
Answer:
882 J
