Homework Statement


An acrobat on skis starts from rest 50.0 m above the ground on a frictionless track and flies off the track at a 45.0° angle above the horizontal and at a height of 10.0 m. Disregard air resistance.

a. What is the skier’s speed when leaving the
track?

b. What is the maximum height attained?


Homework Equations


kinetic energy=1/2 mass*speed^2
potential energy

The Attempt at a Solution


somehow find the kinetic energy of the two height and change it to potential and then with the 45 angle
really need to know how to do it for a quiz
