Question

An object moves along a straight line with an acceleration of 2 m/s​2
. If its initial speed is
10 m/s, what will be its distance covered.

Answer 1

Explanation:

Given:- a = 2m/s² ,u = 10m/s ,v=0m/s

So, By Newton's 3rd Equation of Motion

i.e., 2as = v² - u²

=> 2*2s = 0² - 10²

=> 4s = 100

=> s = 100/4

=> s = 25m

I am not sure though, that the answer may contain negative sign.

So Please check.

Thanks..... Hope it helps......

Answer 2

Answer :

25m

Explanation:

$v^{2}$ - $u^{2}$  =  2as

     $v^{2}$   =  2as

    $10^{2}$  =  2as

  100   =  2 * 2 * s

  100   =    4 * s

      s   =   100 / 4

     s    =    25 m
