Lamar Gant, U. S. powerlifting star, became the first man to deadlift five times his own body weight in 1985. Deadlifting involves raising a loaded barbell from the floor to a position at or near the waist. Determine the work done by Lamar in deadlifting 3.03x10^5 g to a height of 77 cm above the ground.
How much work did Mr. Gant do on the barbell during this amazing feat?
A: 3.12 x 10^3 N x m
B: 3.12 x 10^6 N x m
C: 2.29 x 10^5 N x m
D: 3.12 x 10^5 N x m
E: 2.29 x 10^8 N x m
F: 2.29 x 10^3 N x m

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

i don't know that i agree with that but what's the question ?

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.
