Question

An eagle flying at 15 m/s has 600 J of kinetic energy. About how much is the eagles mass?

Answer 1

Answer:

5.33kg

Explanation:

Given parameters:

Velocity of eagle  = 15m/s

Kinetic energy of the eagle = 600J

Unknown:

Mass of the eagle  = ?

Solution:

The kinetic energy of any body is the energy due to the motion of a body. There are different forms of kinetic energy some of which are thermal, mechanical, electrical  energy.

The formula of kinetic energy is given as;

              Kinetic energy  = $\frac{1}{2}$ m v²

where m is the mass, V is the velocity

   substitute the parameters in the equation;

                       600  = $\frac{1}{2}$ x m x 15²

                     225m  = 1200

                            m  = $\frac{1200}{225}$    = 5.33kg
