A golf ball has been hit off of the tee at an angle of elevation of 30 degrees and an initial velocity of 128 ft/sec. Using the helpful parametric models for projectile motion answer the following questions. x (t) = vo cos(0)t y (t) = hovo sin(0)t - 16t² a.) How long is the ball in the air (hang time)? b.) What is the maximum height of the ball? c.) How far, horizontally, does the ball travel in the air? (round to the nearest foot)
