A pomegranate is launched upward at an angle above the horizontal with a speed and direction such that it reaches a maximum height of 16.8 m above the point it was released. The pomegranate has a speed of 21.9 m/s when it reaches its maximum height. Find the pomegranate's launch speed vo, assuming no air resistance. [Hint: Use the Work-Kinetic energy theorem, setting the work done by the gravity force equal to the change in the pomegranate's kinetic energy.]
