Q#2: What force T, at an angle of 30° above the horizontal, is required to drag a 20lb block to the right at constant speed, if the coefficient of kinetic friction between the block and the surface is 0.20
12. What force T, at an angle of 30∘ above the horizontal, is required to drag a block weighing 20 N to the right at constant speed, as in figure below, if the coefficient of kinetic frictional between block and surface is 0.20. [Ans.: T=4.14N,n=17.9N ]
