Max Height of 2kg Object in Newton Law Problem

[physstudent1]

1. "two objects with masses 5kg and 2kg hang .6 m above the floor from the ends of a cord 6m long passing over a frictionless pulley. Both objects start from rest. Find the maximum height reached by the 2kg object.

Homework Equations

Newton's laws.
Kinematic equations.

The Attempt at a Solution

The answer is around 1.4 but I keep thinking its 1.2m.
My thinking is that the heavier block will fall .6m causing the rope to pull on the lighter block raising it .6m and making the total height of that block .6m + .6m = 1.2m ... I don't know what else to try I tried solving for a and using kinematics but I just got 1.19 which is basically the same thing.

As far as I can see the answer should be 1.2 m . Are you sure you have written down the question properly ?

 

[physstudent1]

yes I am sure maybe a typo in the answers?
