Connected Bodies & Pulleys

A block of mass MM is pulled along a horizontal frictionless surface by a rope of mass m.m. If a force PP is applied at the free end of the rope, the force exerted by the rope on the block is

Show answer and solution

Answer: (d)

  1. System acceleration: a=PM+ma = \dfrac{P}{M + m}.
  2. The rope's force on the block alone gives it this acceleration: T=Ma=PMM+mT = Ma = \dfrac{PM}{M + m}.
  3. So the answer is (d).
