A fly weighing 1 g flies at a speed of 5 m / s at a height of 2 m above the ground. What is the kinetic and potential

A fly weighing 1 g flies at a speed of 5 m / s at a height of 2 m above the ground. What is the kinetic and potential energy of a fly relative to the surface of the earth? What is the mechanical energy of a fly?

Solution:
EK = 0.001 * 25: 2 = 0.0125J
EP = 0.001 * 10 * 2 = 0.02J
EM = EP + EK = 0.02 + 0.0125 = 0.0325J
Answer: 0.02 J: 0.0125 J; 0.0325 J
