A boy throws a paper airplane. It follows a parabolic path as shown in the figure. At the instant the paper
airplane is 2 meters horizontally and 1 m vertically away from the boy, it was observed that it was flying
at a speed of 1.5 m/s and is speeding up by 0.2 m/s^2 (due to the wind). Determine the total
acceleration/deceleration of the paper airplane at this instant.
