Problem 6-47 Dynamics with friction - Part 5 - 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
\(\mu_K = F_K/F_N \\ a_y = 0 \\ F_N + F \sin \theta - mg = 0\)
Correct.
\(F_N + F \sin \theta - mg = 0\)
so
\(F_N = mg - F \sin \theta\)
Before continuing, calculate the value of \(F_N\)
