    Here's a toughy about pulleys and friction

    Nope, this is all the problem says. It's meant to "make us think", but I'm just getting a headache. From what I can gather, the heavier block is on a table, their is a frictionless pulley on the corner of the table, and an empty bucket is hanging on the rope tying the two masses together. Any...

    Here's a toughy about pulleys and friction

    This is my problem: A 28 kg. block is connected to an empty 1.00 kg. bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.45 and the coefficient of kinetic friction between the table and the block is 0.32. Sand is...
