A spring gun at ground level fires a golf ball at an angle of 45%. The ball lands 14 m away. The acceleration due to gravity is g=9.8 m/s². What was the ball's initial speed? For the same initial speed, find the two firing angles that make the range 5 m. m/sec. The initial speed of the ball is (Round to the nearest hundredth.) 10/12/2022 14:12
