Toy train engine rests motionless on a track. One student begins pushing the engine to the right with a force of 2 N. At the same time, another student begins pushing the engine to the left with a force of 5 N. Which of the following best describes the resulting? A. It travels left at a constant speed.
B. It travels left at an increasing speed.
C. It travels right at a constant speed,
D. It travels right at an increasing speed.

see earlier answer

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.
