Calculating Energy and Height of Acrobat on Skis

Click For Summary

Homework Help Overview

The problem involves an acrobat on skis starting from a height and flying off a track at an angle. It focuses on calculating the skier's speed at the point of leaving the track and determining the maximum height attained during the jump.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the conversion of kinetic energy to potential energy and the implications of the angle of departure. There are attempts to clarify the relationship between the heights and the energy calculations involved.

Discussion Status

Some participants express uncertainty about their attempts and seek further guidance. There is a recognition of the need to understand the energy transformations involved, but no consensus has been reached on the approach to take.

Contextual Notes

Participants mention the context of a quiz, indicating a potential constraint on resources or methods available during the assessment.

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
 
Physics news on Phys.org
you got to try it at least man.
 
unless of course they let you using physics forums during your tests. do they do that nowadays?
 
ok i did try i still don't get it
 
never mind solve it
