A mass m₁is connected by a light string that passes over a pulley of mass M to a mass m₂sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of MR². If m₁is 1.00 kg, m₂is 2.00 kg, and M is 4.00 kg, then what is the tension in the string attached to m₁?

M
