a circus clown weighing 170 lbs. is fired from a cannon at 50 degrees above the horizontal. The clown lands in a circular net that has a radius of 15 ft. and located 9.1 ft. above the ground. The closest edge of the net is 114 ft. from the cannon. It takes 3.00 seconds for the clown to travel through the air and land in the exact center of the net. What was the initial velocity of the clown in ft/s?
