Unit 5: Work, Energy and Power

Problem Set C

 

Problem 13:

A 188-gram ball is thrown straight upwards with an initial speed of 33.1 m/s. To what height (in meters) will it rise if the amount of air resistance which it encounters is negligible? 

 

 

 

 

 

0.5 • m • vi2 + m • g • h i + F • d • cos = 0.5 • m • vf2 + m • g • h f

 

General information about work and energy problems is described on the Set C Overview page.

A detailed discussion of how to analyze physical situations using work-energy bar charts is provided online at The Physics Classroom.

A detailed description of the work-energy relationships for situation in which total mechanical energy is conserved is provided online at The Physics Classroom.
