A block of mass slides on a frictionless tabletop. It is connected to a string that passes over a pulley and suspends a mass (Figure 1) . Suppose that the mass on the frictionless tabletop has the value = 2.30 kg Find the value of that gives an acceleration of 2.85 m/s^2 What is the corresponding tension, , in the string? Calculate the ratio T/m2gand show that it is less than 1, as expected
