Ariver has a steady speed of 0.500 m/s. a student swims upstream a distance of 1.00 km and swims back to the starting point. if the student can swim at a speed of 1.20 m/s in still water, how long does the trip take? compare this with the time the trip would take if the water were still.

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.
