The horizontal force applied by the man on the string is F. Determine a. Find the force exerted by the string on the block and acceleration of system. b. Find the tension at the mid point of the string. c. Find the tension at a distance x from the end at which force is applied. Assume that the block is kept on a frictionless horizontal surface and the mass is uniformly distributed in the string.

A man of mass M is standing on a plank kept in a box. the plank and box as a whole has mass m. A light string passing over a fixed smooth pulley connects the man and box. If the box remains stationary find the tension in the force exerted by the man on the plank.
