Problem 6-47 Dynamics with friction - Part 2 - A

A boy drags a huge garbage can of mass \(27\; kg\) along a horizontal driveway at a constant speed of \(1.8\; m/s\). He exerts a force of \(112\; N\) at an angle of \(27^\circ\) above the horizontal. Determine the coefficient of kinetic friction between the can and the driveway.


Accumulated Solution

FBD with all angles, directions and forces indicated.


Correct.

What is the definition of \(\mu_K\) ?

(A)   \(\mu_K = F_K/F_N\)

(B)   \(\mu_K = F_KF_N\)

(C)   \(\mu_K = F_N/F_K\)
