AP Physics C Mechanics Problem

[semaphore12]

<p>One person with mass M
and an object with mass m</p>

<p>there's a rope attached between the person and the object</p>

<p>if the person and the object are on a friction-less surface, and the person pulls on the rope, how far will the person go, and how far will the object go? (before they eventually meet together)</p>

[Maxwellequations]

<p>m moves the distance of Mx length/(m+M) and person moves m x length /(m+M) where length being the length of the rope. because m/M is the ratio of their accelerations.m+M is their total mass. rough explanation.</p>
