Question

Figure (10-E4) shows two blocks of masses m and M connected by a string passing over a pulley. The horizontal table over which the mass m slides is smooth. The pulley has a radius r and moment of inertia I about its axis and it can freely rotate about this axis. Find the acceleration of the mass M assuming that the string does not slip on the pulley.

why is it a/r square

---

T.r = I α(torque)  ; since a= rα => α = a/r

Therefore, T= Ia/r^2
