At the instant under consideration, the cable attached to the cart of mass m1 is tangent to the circular path of the cart. If the upward speed of the cylinder of mass m2 is v2 = 3.0 m/s, determine the magnitude of the acceleration of m1 and the tension T in the cable. What would be the maximum speed of m2 for which m1 remains in contact with the surface? Use the values R = 7.75 m, m1 = 0.8 kg, m2 = 0.9 kg, and β = 31°
