A skier of mass 70 kg is pulled up a slope by a motor-driven cable. a) How much power is required to pull him 100 m up a 30° frictionless slope at a constant
speed of 2 m/s? b) How many horsepower (hp) output must a motor have to
perform this task? *

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.

given values:

mass = 0.3 kg.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

i'm on my way to history not a mistory.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
