Question

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

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
