If you drop a 2.3kg ball from the top of a 44 m high building, how much potential energy will it have just before it hits the ground? Round your answer to the nearest whole number and include an appropriate unit

Sagot :

Answer: Potential energy = 0

Explanation:

The formula for calculating potential energy is expressed as

Potential energy = mgh

where

m = mass of object

g = acceleration due to gravity = 9.8m/s^2

h = height of object above the ground

From the information given,

m = 2.3

h = 44

Just before the object hits the ground, all potential energy is converted to kinetic energy. Thus, the answer is

Potential energy = 0
