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°. At the instant the ball is hit, an instantaneous gust of wind blows against the ball, adding a component of - 15i (f/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. Complete parts (a) through (e). ... a. Find a vector equation for the path of the basebal. r(t) = C • O (Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) b. How high does the baseball go, and when does it reach its maximum height? The baseball reaches its maximum height of feet after seconds. (Round to two decimal places as needed.) c. Find the range and flight time of the baseball, assuming the ball is not caught. The range is feet, and the flight time isO seconds. (Round to two decimal places as needed.)
