Unit 5: Work, Energy and Power

Problem Set B

 

Problem 14:

A 431-kg roller coaster car is moving with a speed of 15 m/s at the top of a 16.4-meter high loop. What is the kinetic energy (in Joules) of the car at the bottom of the loop?  

 

 

 

 

 

Use the equation below to solve this problem. Cancel terms, substitute and solve.

 KEi + PEi + Wnc = KEf + PEf

 

Work and energy principles and mathematical relationships can be reviewed on the Set B Overview page.
