Explanation:

Gravitational potential energy

= mgh = (45kg)(9.81N/kg)(2m) = 882J.

The sled’s potential energy is 882 J.

Potential energy

The potential energy of the sled is calculated using the following formula as shown below;

P.E = mgh

Where;

  • m is the mass of the sled = 45 kg
  • g is acceleration due to gravity
  • h is the height

P.E = 45 x 9.8 x 2

P.E = 882 J

Thus, the sled’s potential energy is 882 J.
