Body a weighs 102 n, and body b weighs 32 n. the coefficients of friction between a and the incline are μs = 0.56 and μk = 0.25. angle θ is 40°. let the positive direction of an x axis be up the incline.

find the acceleration of a if a is moving up 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.
