Kinematics of motion in a straight line — practice question
A ring with mass $0.3\,\text{kg}$ is passed through a horizontal rough rod. The coefficient of friction between the ring and the rod is $0.8$. A force of magnitude $8\,\text{N}$ acts on the ring. It is applied at an angle of $10^\circ$ above the horizontal in the vertical plane containing the rod.
