Problem

In an Atwood machine, blocks of masses 4 kg and 6 kg are connected by a light, inextensible string over a frictionless pulley. Ignore air resistance. What is the magnitude of the acceleration of the system? (a) 4.9 m/s24.9\ \text{m/s}^2 (b) 2.0 m/s22.0\ \text{m/s}^2 (c) 0.20 m/s20.20\ \text{m/s}^2 (d) 9.8 m/s29.8\ \text{m/s}^2
