Math Problem Statement
There are two blocks with masses 3.5kg and 1.3 kg connected by a massless string, which changes direction over a massless, frictionless pulley. The two inclined planes are made of different materials with different coefficients of kinetic friction, 4.6 and 0.7 The inclines are. Say the system of blocks has velocity toward the right. Find the magnitude of tension in the string.
