Slanting Surfaces Without Friction: A system consisting of blocks, a light frictionless pulley, a frictionless incline, and very light connecting wires is shown in the figure. The wires pull on the left-hand blocks parallel to the surface of the ramp. The 9.0-kg block accelerates downward when the system is released gently from rest.(a) What is the magnitude of the acceleration of the 9.0-kg block?(b) What is the tension in the wire connecting the two blocks on the incline?
What will be an ideal response?
