Solve the problem. Assume projectile is ideal, launch angle is measured from the horizontal, and launch is over a horizontal surface, unless stated otherwise.A baseball is hit when it is 3.4 ft above the ground. It leaves the bat with an initial velocity of 
at a launch angle of 23°. At the instant the ball is hit, an instantaneous gust of wind blows against the ball, adding a component of -13.5i (ft/sec) to the ball's initial velocity. How high does the baseball go? Round your answer to the nearest tenth.
A. 54.7 ft B. 46.8 ft C. 50.2 ft D. 52.2 ft
