Answer to Question #255072 in Physics for Roger3

Question

A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m, as

shown in Figure. A horizontal force acts on one end of the rope. Assuming that the sag is

negligible, Find the acceleration of rope and block, (c) the force on the block from the rope, and

(d) the tension in the rope at its midpoint.

Answer 1

The acceleration is

$$a=F/m.$$

The force on the block from the rope is F.

The tension in the rope at the midpoint is F.
