A toy airplane is flying in a straight horizontal (parallel to the ground) path with a speed of vi=33 m/s. Suddenly, the airplane's engines stop (at t=0). Using an x axis that is horizontal and along the plane's original velocity and a y axis that is vertical with positive away from the ground, the airplane now has an acceleration given by the following expressions: ax(t)=−t2/C ay(t)=−g[1−vx(t)/vi] where C=2690s4/m and vx(t) is the x component of the airplane's velocity. The airplane crashes 34.87 seconds after the engines stop.
