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) = vy cos(0)t y (t) = ho + vp sin(6)t 16t 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) Given the same type of golf ball scenario with an equation y = -0.004x2 + 1.6x, horizontal distance of 400 feet, maximum height of 160 feet, and using the helpful projectile motion formulas below, answer the following. x (t) = v. . cos(0).t y(t)=h + v. sin(0).t-1612 a.) What is the angle at which the ball takes off? [ Select ] V b.) How long is the ball in the air? [ Select ] c.) What is the ball's speed when it hits the ground? [ Select ] V
