How do you use errors in mass and velocity to find the errors in starting and ending kinetic energy?

Equation for KE = 1/2mv^2

Error in m = 0.179kg +/- 0.005 kg

Error in velocity starting = -0.0648m/s +/- 0.011 m/s

Error in velocity ending = 0.259m/s +/- 0.020 m/s

How many structures can you find to use as a starting dataset if you wanted to study how proteins interact with DNA. Assume that you will require only high resolution structures for the study (at least 2.5 Angstroms resolution). For the study, you plan to use structures that were only solved by X-ray crystallography.
