You are to make four straight‐line moves over a flat desert floor, starting at the origin of an xy coordinate system and ending at the xy coordinates (−140 m, 30 m). the x component and y component of your moves are the following, respectively, in meters: (20 and 60), then (bx and −70), then (−20 and cy), then (−60 and −70). what are (a) component bx and (b) component cy? what are (c) the magnitude and (d) the angle (relative to the positive direction of the x axis) of the overall displacement?

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.
