Chemistry 2 Question-please help!

Can someone please explain how to do this question

The Heisenberg uncertainty principle is important in understanding the concepts of quantum mechanics. One form of this principle can be expressed as follows:

delta x * delta p >h/4pie

where h is Planck's constant The hydrogen atom has a radius of ~ 0.05 nm. Assuming the uncertainty in the position of an electron, Ax, is about 5 x 10"13 m (1% of the radius of H atom),
calculate the uncertainty in the velocity of the electron.

The textbook (zumdahl) goes through a similar problem. Check it out
