A sled is at rest at the top of a 2 m high slope. The sled has a mass of 45 kg. The sled's potential energy is

Verified Answer :

PE = mgh = (45)(9.81)(2) J
PE = 882.9 Joules

We have to apply potential energy formula:


\(P.E = mgh\)

where m is the measure of mass, g is gravitational acceleration which is always fixed and h indicates height. Plugging the data into formula, we find that:


\(P.E=mgh=45*9.8*2=882 Joules\)
