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

Explanation:

Step1: Identify values

$m = 45$ kg, $g= 9.8$ m/s², $h = 2$ m

Step2: Substitute into formula

$PE=mgh=45\times9.8\times2$
$PE = 45\times19.6$
$PE=882$ J

Answer:

D. 882 J
