A0.100-kilogram apple falls from a height of 1.50 meters to 1.00 meters. ignoring frictional effects, what is the kinetic energy of the apple at this height?

The kinetic energy of the apple at this height is 0.49 J.

Explanation:

Mass of apple, m = 0.1 kg

It falls form a height of 1.5 meters to 1 meters. We need to find the kinetic energy of the apple at this height. As the apple is falling, the decrease in potential energy is equal to the increase in kinetic energy. Using the conservation of energy as :

So, the kinetic energy of the apple at this height is 0.49 J. Hence, this is the required solution.

i was thinking more like reflects green light, just not sure
