3. Aurora hit a baseball with an initial velocity of 100 feet per second at an angle of 30° with the horizontal. The ball hit her bat when the ball was 3 feet above the ground. The back wall is 200 feet away standing at a height of 9 feet. Answer: a. b. a. No one interferes with the ball. How long does it take the ball to reach the back wall? Round your answer to the nearest hundredth of a second. b. Does the ball go over the back wall? Explain how you know if it does or does not. Note: if necessary, use your rounded answer from Part (a) in your calculations.
