4. During a thunderstorm, a tornado lifts a car to a height of 125 m above the ground. Increasing in strength, the tornado
flings the car horizontally with an initial speed of 90 m/s.
a. How long does the car take to reach the ground?
b. How far horizontally does the car travel before hitting the ground?

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.
