Question 1182716
.
<pre>

To find the time, use the formula for the speed gained by uniformly accelerated body

      v = at.


where "a" is the acceleration; t is the time;  v is the speed.


In your case  a = 5 m/s^2, v = 100 m/s  are given,  so


    t = {{{v/a}}} = {{{100/5}}} = 20 seconds.



Having the acceleration and time, you can now find the distance


    d = {{{(a*t^2)/2}}} = {{{(5*20^2)/2}}} = {{{(5*400)/2}}} = 5*200 = 1000  meters.    <U>ANSWER</U>

I used standard formulas from Physics (kinematics).
