Unit 5: Work, Energy and Power

Problem Set B

 

Problem 11:

A 2.2 kg physics cart starts from rest at the top of a .62-meter high incline. Determine the kinetic energy (in Joules) of the cart at the bottom of the hill.  

 

 

 

 

 

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

 KEi + PEi + Wnc = KEf + PEf
