A circus performer launches himself from a springboard with an initial velocity of 21 m/s at an angle of 75° toward a platform hanging 20 m above the ground, a horizontal distance of 15 m away from the springboard. Does he land on the platform or fall back down to the ground? Make a complete model, including the maximum height he reaches, the time of flight, and his final velocity (direction and magnitude) just before landing. Show all your work and explain your reasoning. Take g =9.8 m/s².
