Free-Body Diagram With Friction
A hockey puck slides across a frictionless ice surface and enters a rough region, where it slows down due to a kinetic friction force. Which of the following correctly identifies all the forces acting on the puck while it is slowing down?
A
Two forces: normal force and friction
B
Three forces: weight, normal force, and applied force
C
Four forces: weight, normal force, friction, and inertia
D
Three forces: weight, normal force, and kinetic friction
