A bird is flying in the air at a 4 m/s. If the mass of the bird is 7kg what is it’s kinetic energy

yaroslaw [1]

Answer: The kinetic energy of the flying bird is 56 Joules.

Explanation:

Mass of the bird = 7 kg

Velocity of the flying bird = 4 m/s

Kinetic energy of the bird will be given by :

$K.E.=\frac{1}{2}mv^2$

$K.E.=\frac{1}{2}\times 7 kg\times (4 m/s)^2=56 Joules$

The kinetic energy of the flying bird is 56 Joules.
