An airplane releases a ball as it flies parallel to the ground at a height of 145 m as shown in the figure. If the ball lands on the ground precisely 145 m from the release point, compute the speed v of the plane. Neglect any effects due to air resistance, and utilize g = 9.81 m/s2 for the acceleration due to gravity.
