Answer 1

Answer:

The value is $s =197.88 \ m$  

Explanation:

From the question we are told that

    The  impulse is  $I = 950 \ N\cdot s$

    The mass is  $m = 12 \ kg$

     The time t =  5 s

Generally impulse is mathematically represented as

         $I = F * t$

=>       $F = \frac{I}{t}$

=>       $F = \frac{950 }{ 5 }$

=>       $F = 190 \ N$

Generally force is mathematically represented as

      $F = m * a$

=>    $a = \frac{F }{ m }$

=>     $a = \frac{190 }{ 12 }$

=>     $a = 15.83 \ m/s^2$

Generally from kinematic equation , the distance covered is  

      $s = ut + \frac{1}{2} * at^2$

Here  u is the initial velocity of the cart and the value is $u = m/s$

=>   $s = 0 * 5 + \frac{1}{2} * 15.83 * 5^2$  

=>   $s =197.88 \ m$
