Vector vector a has a magnitude of 29 units and points in the positive y-direction. when vector vector b is added to vector a , the resultant vector vector a + vector b points in the negative y-direction with a magnitude of 18 units. find the magnitude of vector b ?

be subject to a force andchange its motion

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.
