A truck of 4000 Kg mass and tom length Its center of mass 4 m behind the start of It where we put weight of 1400 xg so that the center of mass will be right the middle of the truck.

explanation:

less than one you can't create energy

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.
