1. Calculate the potential energy in the following cases a) A 10 kg mass moves up 2.4 m b) A 589 mg mass moves up 325 cm c) A 10 N stone is lifted up 10 m d) A 10 kg mass sitting on the roof of a house that is 15 m above the edge of a 120 m high cliff 2. A 2.0 kg watermelon rolls off a 0.75 m high onto a chair 0.45 m high before finally landing on the floor. While it is on the table what is the gravitational potential energy of the watermelon relative to: a) the table b) the chair c) the floor 1.
