Asked by Jesus

A bird has a mass of 0.2 kg and is flying 10 m above the ground with a speed of 7 m/s. What is the total mechanical energy of the bird? Acceleration due to gravity is g = 9.8 m/s2.
Answered by MathMate
Total mechanical energy
= KE + PE
(assume PE at ground level = 0)

KE=(1/2)mv²
PE=mgh
h=height above ground in m
v=velocity in m/s
