A quadrocopter weighing 250 g moves at a height of 4 m and at a speed of 2 m / s. Determine the total mechanical energy of the quadcopter relative to the Earth
Given:
m = 250 g = 0.25 kg (Translated in SI)
h = 4 m
v = 2 m / s
Em = Ek + En
Em = mv ^ 2/2 + mgh
Em = 0.25 * 4/2 + 0.25 * 10 * 4
Em = 10.5 J
Answer: 10.5 J
