The mass of the bucket attached to the pulley shown in the diagram below is gradually increased by adding sand to the bucket. At some point, the 10 kg block begins to move. The values for the coefficients of static and kinetic friction are 0.60 and 0.50 respectively. a. What is the mass on the bucket and sand at this point? b. What is the acceleration of the block up the slope?
