Chapter 22, Problem 24P
A proton accelerates from rest in a uniform electric field of 640 N/C. At one later moment, its speed is 1.20 Mm/s (non-relativistic because v is much less than the speed of light). (a) Find the acceleration of the proton. (b) Over what time interval does the proton reach this speed? (c) How far does it move in this time interval? (d) What is its kinetic energy at the end of this interval?

The electric field is zero everywhere except in the region 0≤x≤4.00 cm, where there is a uniform electric field of 110 N/C in the +y direction. A proton is moving in the +x direction with a speed of v = 1.00×10^6 m/s. When the proton passes through the region 0≤x≤4.00 cm, the electric field exerts a force on it.
1)When the x coordinate of the proton’s position is 4.00 cm, what is the y component of its velocity?(Express your answer to three significant figures.)
