1. The problem statement, all variables and given/known data A block of mass 30 kg rests 12 m from the bottom of an inclined plane that is at an angle of 60 to the horizontal. It is connected by a rope of negligible mass via a frictionless pulley to a bucket of mass 5 kg of water, hanging vertically as shown in Fig. Q3. The static and dynamic coefficients of friction between the block and the plane are 0.7 and 0.4, respectively. Water leaks from the bucket at a constant rate of 20 g s-1. Show that the block will not initially move up or down the incline if the above is unclear, it is question 3 b on past paper that is attached. 2. Relevant equations sohcahtoa equations Friction = mu*R R = mgcos60 F = ma mu(static max) = .7 mu(dynamic) = .4 3. The attempt at a solution after doing a free body diagram trying to look at whether the block can go down, i got the net force on the block is: Fnet = component of gravity - tension from bucket - friction Fnet = Mblock*gsin60 - Mbucket*gsin60 - Mblock*mu*gcos60 = 30gsin60 - 5gson60 - 5*.7*gcos60 = 121.3 N the question is saying that there should be no net positive force (since the static friction should go up and cancel it, but using max static friction i'm still getting a net force).
