Problem 6-47 Dynamics with friction

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


Considering the forces acting on the can, what is the FBD of the can?

Four possible FBDs; A, B, C, D.

(A)

(B)

(C)

(D)
