1. Homework Statement
To complete your master's degree in physics, your advisor has you design a small, linear accelerator capable of emitting protons, each with a kinetic energy of 11.3 keV. (The mass of a single proton is 1.67*10^(-27) kg.) In addition, 1.00*10^9 protons per second must reach the target at the end of the 1.80-m-long accelerator.
(a) What the average power must be delivered to the stream of protons?
_____μW
(b) What force (assumed constant) must be applied to each proton?
______ N
(c) What speed does each proton attain just before it strikes the target, assuming the protons start from rest?
_______ m/s
2. Homework Equations
Work - kinetic energy theorm
Work formula
3. The Attempt at a Solution
Ok so I said KE= Work total or KE=Fd. I have all of those to get the force for question 2, then plug it into my power equation P=Fv for number 1 then W=1/2mv^2 for number 3... but I'm all mixed up on the units... so any help on that would be great. And I'm not so sure my way is right either...
