Unit 3: Motion in Two-Dimensions

Problem Set E

Problem 15:

Use the diagram below to assist in your problem solving. A 3.73-kg object is placed upon an inclined plane which has an incline angle (theta) of 22.3 degrees (theta). If the object slides down the inclined plane with a constant velocity, then what is the force of friction (in Newtons) acting upon the object?

• Read the problem carefully and diagram the physical situation (free-body diagram)
• Identify known and unknown information in an organized manner (write on diagram)
• Take the time to plot out a strategy prior to beginning the solution
• Identify an appropriate formula to use
• Perform step-by-step algebraic manipulations

A discussion of basic principles related to Set E and to inclined plane problems is provided on the Set E Overview page.

Detailed information and examples of inclined plane problems are available online at The Physics Classroom.
