1. The problem statement, all variables and given/known data A proton (mass m = 1.67x10^-27 kg) is being accelerated along a straight line at 2.0x10^15 m/s^2 in a machine. The proton has an initial speed of 2.4x10^7 m/s and travels 2.5 cm. (a) What is its speed? (b) What is the increase in its kinetic energy? 3. The attempt at a solution Is it ok to have no idea where to begin? I know F=ma, and that V=Vo+1/2at... but I can't see how that helps. Help me begin?
