4. Tim is walking down the aisle of a speeding bus and tosses a coin in the air. Matthew is standing on the sidewalk outside.
a. Draw the trajectory of the coin from Tim's frame of reference.

b. Draw the trajectory of the coin from Matthew's frame of reference.

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.
