I was practicing for Test 3. I cam upon a test problem of:

What is the approximate uncertainty in the velocity of a proton known to remain within a nucleus of diameter 1 * 10^-15 m? What kinetic energy would the proton (mass approximately 1.6 * 10^-27 kg) have at this velocity?

Unfortunately, my book does not have the equation needed. On the test, can I omit this question?

This equation belongs on the 4th test, and wouldn't be included on the 3d.
