A man travels 15 km east before turning around and heading 5 km west. What is his displacement? A) 20 km
B) 10 km west
C) 10 km East
D) 20 km East

10 km East

Displacement is the shortest path between two points.

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.
