Unit 3: Motion in Two-Dimensions

Problem Set E

 

Problem 12:

Use the diagram below to assist in your problem solving. A 401-Newton force is being applied at an upward angle of 30 degrees (theta) to accelerate a 40.21-kg box across a horizontal surface. If the coefficient of friction ('mu') between the surface and the object is 0.245, then determine the acceleration (in m/s/s).

 

  

 

 

 

A discussion of basic principles related to Set E and Fnet = m•a problems is provided on the Set E Overview page.

Detailed information and examples of Fnet = m•a problems are available online at The Physics Classroom.
