A proton accelerates from rest in a uniform electricfield of 670 N/C. At some later instant,its speed is 1.60 X106 m/s(nonrelativistic, because v is much less than the speed oflight).
a) Find the acceleration of the proton.b) After what time interval does the proton reach this speed?c) How far does the proton move in this time interval?d) What is its kinetic energy at the end of this time interval?
