A 1.2-kilogram mass is projected from groundlevel with a velocity of 30 m/s at some unknown angle above thehorizontal. A short time later, after being projected, the massbarely clears a 16-meter tall fence. Disregard air resistance andassume the ground is level. What is the kinetic energy of the massas it clears the fence?
