Provide an appropriate response.A baseball is hit when it is 3.1 feet above the ground. It leaves the bat with an initial velocity of 141 ft/sec at a launch angle of 22°. At the instant the ball is hit, an instantaneous gust of wind blows against the ball, adding a component of -10i ft/sec to the ball's initial velocity. Find the range and flight time of the ball, assuming that the ball is not caught.
