A block of mass m = 331 g is dragged with a string across a rough horizontal table. The string tension is T = 3.59 N, and it pulls upward at an angle of ¦Õ = 43.0¡ã with the horizontal. At one particular instant the block is moving at a speed of v = 6.90 m/s. The coefficient of kinetic friction between the block and the table is ¦Ìk = 0.609.
