In a circus act, a 78 kg clown is shot from a cannon with an initial velocity of 19 m/s at some unknown angle above the horizontal. A short time later the clown lands in a net that is 4.4 m vertically above the clown's initial position. Disregard air drag. What is the kinetic energy of the clown as he lands in the net?
