A ski jumper starts from rest 44.0 m above the ground on a frictionless track, and flies off the track at an angle of 45.0° above the horizontal and at a height of 14.0 m from the ground. Neglect air resistance.
(a) What is his speed when he leaves the track?
(b) What is the maximum altitude he attains after leaving the track?
(c) Where does he land relative to the end of the track?
