A flower pot with a mass of 1.2 kg is sitting on a ninth story windowsill 30 meters above the ground. How many joules of energy does the flower pot have? Is the energy potential energy or kinetic energy?

Pt.2
USE THE QUESTION ABOVE: The owner of the flower pot gave it to a friend who lived on the second floor of the
apartment building. This person also put it on their windowsill which was 6 meters above the ground? Now how

Answer:

(assuming gravity = 10m/s2)

answer for part 1 :

the pot will possess potential energy and not kinetic energy.

the energy which the pot possess is = PE of the pot

PE = mgh = 1.2x 10 x 30 = 360 J

answer for part 2 :

PE = mgh = 1.2 × 10 × 6 = 72 J

Explanation:

the PE of a body is not due to its state of motion, its due to the state of rest of the body. when the body starts moving it possess kinetic energy.
