A60-kg (including the passenger) sled is subject to a net force of 20 n pushing in the direction of the sled’s motion as it is moving over a horizontal surface for a distance of 11 m after having started from rest. at this point the sled is released as it starts down a 10.0° incline. however, the snow is not very deep, and the sled stops after having moved an additional 35 m. what is the work done by friction while the sled is on the incline?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
