A Hollywood daredevil plans to jump the canyon shown in the figure on a motorcycle. There is a 15. m drop and the horizontal distance originally planned was 60. m but it turns out the canyon is really 65.7 m across. If he desires a 3.1-second flight time, what is the correct angle for his launch ramp (deg)? What is the correct angle for his landing ramp (give a positive angle below the horizontal)? is his predicted landing velocity. (Neglect air resistance.)
