We are given:
We are given:m1 = 300 grams
We are given:m1 = 300 gramsm2 = 500 grams
We are given:m1 = 300 gramsm2 = 500 gramsh1 = h2 = 2 meters
We are given:m1 = 300 gramsm2 = 500 gramsh1 = h2 = 2 metersWe have to determine the potential energy of both toy cars:

This is because mass is directly proportional to the potential energy of an object.
