Question

A baseball is hit when it is 3 ft above the ground. It leaves the bat with initial velocity of 181 ft/sec at a launch angle of 18-degrees. At the instant the ball is hit, an instantaneous gust of wind blows against the ball, adding a component of -15i (ft/sec) to the ball's initial velocity. A 8 ft. high fence lies 375 ft from home plate in the direction of the flight. The acceleration due to gravity is g=32 ft/sec^2. 

Please see the attached image for questions:

c. Find the range and flight time of the baseball, assuming the ball is not caught.
The range is

feet, and the flight time is
seconds.
d. When is the baseball 4 ft high? How far (ground distance) is the baseball from home plate at that height?
The baseball is 4 ft high after

The baseball is
feet or
feet from home plate when it is 4 ft high.
(Round to two decimal places as needed. Use ascending order.)
e. Has the batter hit a home run? Explain.
O A. No because the ball does not reach the wall.
O B. Yes because the ball goes over the wall.
C. No because the ball hits the wall.
