A 70-kg ski jumper starts from rest 59 m above the ground on an icy track and flies off the track at an angle of 31° and at a height of 13 m above the ground. All types of friction are negligible in this problem.
(a) With what speed does the skier leave the track?
(b) What is the kinetic energy of the skier at the maximum height the skier reaches during the jump?
(c) What is the maximum height the skier attains during the jump?
