A pot plant falls off the balcony of an apartment. The balcony is 20 m above the ground and the pot plant has a mass of 2 kg. After falling a distance of 2 m from the balcony, the pot plant has a velocity of 6,26 m·s-1 . Ignore the effect of air resistance. 5.1

Calculate the gravitational potential energy of the pot plant before it begins to fall. 5.2 Calculate the total mechanical energy of the pot plant after it has fallen two meters. 5.3 Is this a closed system?
Explain your answer. 5.4 Calculate the speed with which the pot plant hits the ground.
