In this three body system total kinetic energy remains constant:


If we assume that upwards movement is positive and downwards movement is negative the formula is:

Formula for kinetic energy is:

Now we have:

We got two solutions: positive and negative. The speed is 5.04 m/s and direction can be upwards and downwards.
