Homework Help: Find the force of the rope on the block

  1. Jan 25, 2007 #1
    A block of mass 'M' is pulled along horizontal frictionless surface of a rope of mass 'm'. Force 'P' is applied at the end of rope. Find the force which the rope exerts on the block.

    My attempt:
    The total mass = M+m
    Force P=(M+m)*a ------------ (i)
    Force exerted on block = ma
    a=P/(M+m)
    Force on block=mP/(M+m)

    Am i correct? :grumpy:

    Thread moved to homework. Based on your number of posts (not a newbie mistake), I'm giving a 0-point warning for posting a homework question in the general forums. Oh, and your answer looks correct to me.
