## Homework Statement

An airplane descends in a circular pattern with a constant radius of 250 meters. The airplane has a horizontal speed of 75 m/s (constant) and a downward

speed of 5 m/s, which is increasing at a rate of 2 m/s

^{2}

Determine the acceleration of the airplane.

## Homework Equations
