WE KNOW THAT THIRD EQUATION SAYS THAT - v² - u² = 2*a*s
 v =50 m/s
 u = 0
 s = 0.250 m

THEREFORE , 
        50² - 0² = 2*a*0.250
        a = 2500 / 0.250
           = 5000 m/s²

WE KNOW THE FIRST EQUATION SAYS THAT - v = u + a * t
v = 50 m/s
u = 0
a = 5000 m/s²

THEREFORE ,
   50 = 0 + 5000 * t
   t = 50 / 5000
   t = 0.01 s
