# 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

Correct.

What is the definition of $\mu_K$ ?

(A)   $\mu_K = F_K/F_N$

(B)   $\mu_K = F_KF_N$

(C)   $\mu_K = F_N/F_K$
