A proton (mass ) is being accelerated along a straight line at in a machine. If the proton has an initial speed of and travels 3.5 cm, what then is (a) its speed and (b) the increase in its kinetic energy?

You need to specify the acceleration and also provide the missing initial speed following the word "of".

You will also need the mass of the proton, which you can always look up.
