A700 g peregrine falcon dives toward the ground from a height of 80 m and has a kinetic energy of 2,835 j. what is its speed?

Kinetic energy is gven by

Hence the velocity can be found by

or =  = 90m/s

Explanation:

The kinetic energy is the energy due to motion and is given by the kinetic energy equation KE = 1/2mv^2

It is the energy required to stop a body in motion and as seen from the equation, objects with large speed or mass have larger amount of kinetic energy or a large object effect can be made milder by lowering its speed so also a small object can increase its effect, for example a bullet by increasing its speed
