A rope with mass is attached to a block with mass as in Figure P5.42. The block rests on a frictionless, horizontal surface. The rope does not stretch. The Free end of the rope is pulled to the right with a horizontal force .
(a) Draw force diagrams for the rope and the block, noting that the tension in the rope is not uniform.
(b) Find the acceleration of the system in terms of .
(c) Find the magnitude of the force the rope exerts on the block.
(d) What happens to the force on the block as the rope's mass approaches zero? What can you state about the tension in a light cord joining a pair of moving objects?
Two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. Block A has mass 17.0 kg , and block B has mass m.
A constant horizontal force F = 60.0 N is applied to block A (Figure 1) . In the first 5.00 s after the force is applied, block A moves 18.0 m to the right.
While the blocks are moving, what is the tension T in the rope that connects the two blocks?
A block of mass is pulled along a rough horizontal surface by a rope as shown in the figure below. The tension in the rope is and the force of friction between the block and the surface is . If the block travels a distance of along the surface in , find:
(a) the work done by the tension in the rope.
(b) the work done by the force of gravity.
(c) the work done by the normal force.
