How can we increase the gravitational potential energy of the car?

• Strap a boulder to the car so that it weighs more.

• Keep the length of the hill at 50 m but only 5 m tall.

• Take the interior out of the car so that the car has less mass.

• Keep the hill at 10 m tall but increase the length of the hill so that the car has farther to roll.
