Unit 8: Newton's Laws Applications

Problem Set C

 

Overview:

Problem Set C targets your ability to use the a combination of Newton's second law of motion and kinematic equations in order to analyze the motion of objects. Most all of the problems involve objects which are moving in the presence of friction. Thus, the coefficient of friction value will have to be used to determine the amount of friction force. Problems within the set fall into three basic types:

 

 

 

There are at least seven skills or conceptual understandings which you must have to be successful on Problem Set C. They include ...
