Check the consistency? (Physics-related)?

[-lil'rose-]

Check the consistency: d = st + at^3

d = distance
s = speed
t = time
a = acceleration

Thanks in advance!

[Charles G]

d=st+at^3

where: s=d/t
a=d/t^2

d=(d/t)t+(d/t^2)t^3

d=d+dt

1=1+t

t=0

There is your consistency

Your equation is totally wrong. It should be

d = 1/2 at^2
