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

the correct answer is is 0.0688 m/sec^2
Please help me to find the error in my solution
