A proton accelerates from rest in a uniform electric field of 630 N/C. At one later moment, its speed is 1.00 Mm/s (nonrelativistic because v is much less than the speed of light). (a) Find the acceleration of the proton. m/s² (b) Over what time interval does the proton reach this speed? (c) How far does it move in this time interval? m (d) What is its kinetic energy at the end of this interval?
