Which situation would result in a decrease of 39.2 ) in the described object's gravitational potential energy?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

answer; how far out of place which the object finished relative to the starting location;

b. a lightning bug, plug of grass, and a worm

the ima (higher than 1m) will be greater than the ima with the height of 1m.
