A 30.5 kg block is connected to an empty 1.00 kg bucket by a cord running over a frictionless pulley (Fig. 4-57). The coefficient of static friction between the table and the block is 0.470 and the coefficient of kinetic friction between the table and the block is 0.320. Sand is gradually added to the bucket until the system just begins to move.
(a) Calculate the mass of sand added to the bucket in kg.
(b) Calculate the acceleration of the system in m/s/s.© BrainMass Inc. brainmass.com October 9, 2019, 10:00 pm ad1c9bdddf
The solution works on a pully system with kinetic and static friction.
