At time t = 0, & golf ball is shot from ground level into the air, as indicated in Fig. 4-18a. The angle θ between the ball\"s direction of travel and the positive direction of the x axis is given in Fig. 4-18b as a function of time /. The ball lands at t = 6.00 s. What is the magnitude v6 of the ball\"s launch velocity, at what height (y – y0) above the launch level does the ball land, and what is the ball\"s direction of travel just as it lands?
