A body was found in a river by a local hiker at 7:25 PM on October 14th. The medical examiner investigated the body and determined she drowned 12 hours prior to being found. A local homeowner was able to view video footage which showed her disappearing in the

river roughly eight hours and 20 minutes prior to being found. The medical examiner then discussed how the water can effect the time

of death in terms of body cooling.

newton's first law of motion

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.
