Pulley in Physics - pulley tension problems with solution

cylinder - equations to solve pulley tension problems Only one equation and that is along Y-axis. W2 - T = ma mg - T = ma ……………….. (3) Now combining equation 2 and 3, we get mg - Ma = ma or, a = (mg) / (M+m) ——————- (4) Here in equation 4, we get the expression of the acceleration of the cylinder and the cart.
