Question 1182716: A car starting from rest is given a constant acceleration of 5m/s^2. (a) In how many seconds will it attain a velocity of 100 m/s^2? (b) How far will it have traveled in this same time?

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 =  =  = 20 seconds.



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


    d =  =  =  = 5*200 = 1000  meters.    ANSWER

The problem is solved: all questions are answered.

---------------

I used standard formulas from Physics (kinematics).
