Avector has an x-component
of -309 m and a y-component
of 187 m.
find the direction of the vector.

Explanation:

Let a be the direction

tan a= y-comonent/x-component

tan a = 187/-309

tan a = -0.605

a= tan^-1(-0.605)

a = -31.18°

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.
