Using the image at what point is there maximum mechanical energy a. Points 1 and 5
b. Points 1-5 excluding point 3 because it has maximum potential energy
c. Point 4
d. There is equal amount of mechanical energy at each point

D

Explanation:

from the diagram, PE=KE and they both are equal to zero at each point.

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.
