A 28bullkg block is connected to an empty 1bullkg bucket by

Question

Solve the all parts of given question:

Question: A 28•kg block is connected to an empty 1•kg bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.50and the coefficient of kinetic friction between the table and the block is 0.30.

Part I: Find the acceleration of the system if 6.5•kg of sand is put into the bucket.

m/s²

Part II: Find the acceleration of the system if 7.8•kg more sand is added to the bucket.

m/s²

I just want the right answer, Thanks!
