Aroller coaster car rapidly picks up speed as it rolls down a hill. as it starts down the hill, its speed is 4 m/s. but 3 seconds later, at the bottom of the hill, its speed is 22 m/s. what is its average acceleration?

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

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.
