Physics 163

Unit 3: Motion in Two-Dimensions

Problem Set E

Problem 11:

(Referring to the previous problem.) Determine the coefficient of friction ('mu') for the above surfaces. Enter your answer accurate to the third decimal place.

• 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 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.
