Question

A block with mass m₁ hangs from a rope that is extended over an ideal pulley and attached to a second block with mass m₂ that sits on a ledge slanted at an angle of 20. Suppose the system of blocks is initially held motionless and, when released, begins to accelerate.

(a) If m₁ = 5.00 kg, m₂ = 3.75 kg, and the magnitude of the acceleration of the blocks is 0.140 m/s², find the magnitude of the kinetic frictional force between the second block and the ledge. ?N.

(b) What is the value of the coefficient of kinetic friction between the block and the ledge?
