Hello everyone.... I need ur help in the following problem

A perfect rope connects a 20 kg block to a 30 kg block. The rope passes over a perfect

pulley at the top of a 53 ° incline. The 30 kg block rests on the incline and the 20 kg

block hangs from the pulley. The blocks start from rest. Calculate the acceleration of

either block. (µ = 0.2)

F=ma

Fk= N*uk
