1 1 point Two blocks are attached to one another by a rope that passes over a frictionless pulley as shown in the figure. The mass of block A is 6 kg, the mass of block B is 3 kg, and the mass of the pulley is 7 kg. The pulley and can be modelled as a uniformly dense solid cylinder rotating around an axis through its center. The surface along which block A slides is frictionless, the rope passes over the pulley without slipping, and 0=26. What is the magnitude of the acceleration of block A (in m/s)? A B Type your answer...
