There are five constant acceleration formulae, each one omits one of the variables. I suggest you learn them off by heart.

v = u + at

v^2 = u^2 + 2as

s = ut + 0.5at^2

s = vt - 0.5at^2

s = (u + v)t / 2

u = initial velocity (m/s)

v = final velocity (m/s)

s = distance or displacement (m)

a = acceleration (m/s^2)

t = time (s)

speed = gt + u you dont een need the objects weight... max falling speed is the terminal velocity
