A proton accelerates from rest in a uniform electric field of $630\frac{N}{C}.$ At one later moment, its speed is $1\mathrm{.}60M\frac{m}{s}($nonrelativistic because $v$ is much less than the speed of light$).$

$($a$)$ Find the acceleration of the proton.

$q,$

$\frac{m}{s^2}$

$($b$)$ Over what time interval does the proton reach this speed?

$$ s

$($c$)$ How far does it move in this time interval?

$$ m

$($d$)$ What is its kinetic energy at the end of this interval?

$1$ J
