Abird with a mass of 1.5 kg flies at a rate of 4.0 m/s. what is the kinetic energy of the bird?

The answer is 12 J.

The kinetic energy (KE) of an object is expressed as the product of half of the mass (m) of the object and the square of its velocity (v²):


The unit of the kinetic energy is Joules (J = kg · (m/s)²).

It is given:
m = 1.5 kg
v = 4 m/s

It is unknown:
KE = ?

Thus:






Therefore, the kinetic energy of the bird is 12J.
