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.

  • physics -

    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
