Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Please give me the correct answer, please. Thank you. This is my last attempt.
An airplane is flying straight and level at a speed vo = 150 mph and with a constant time rate of increase of speed v = 20 ft/s, when it starts to climb along a circular path with a radius of curvature p = 2000 ft. The airplane maintains i constant for about 30 s. Determine the acceleration of the airplane after it has traveled 280 ft along the path and express the result in the Cartesian component system shown. The acceleration of the airplane after it has traveled 280 ft is a = ( i + 29.85 ) ft/s2. 19.93
