distance a ball dropped from building with gravity at 9.8m/s2 and time of 8 seconds?

When you drop an object from some height above the ground, it has an initial velocity of zero. Simple equations allow you to calculate the velocity an object falls after a given period of time and the velocity it reaches at a given displacement. The equations assume that air resistance is negligible.

Vo = initial velocity = 0 (m/s) 

x = vertical displacement 

t = time and 
a = gravitational constant = 9.8 meters per second squared (m/s2) 
x= initial velocity * time + 1/2 acceleration * time squared 
    = Vot + (1/2)at2]]] 
    = (0*8) + (1/2)(9.8)(8)(8) 
    = 313.6 meters (metric)
