I know you need to use suvat.
s=? u=0 v=? a=? t=?
I am confused because of this ^ . I just need those values please help. Just suvat values.

s = ?
u = 0
v = t(1-t^2)
a = ?
t = t

suvat only applies where you have constant acceleration, implying velocity is a linear function of time; this is not the case here.

You have v as a function of t and just need to find its maximum value. This is no different to having y as a function of x, and needing to find the max value of y; which I would presume you're covered.

I've don't have the book, so no idea if it's that chapter. But if you've not yet covered the material, then it's not a good idea to attempt the question.

Also fully worked solutions are against the forum rules - see sticky thread at top of forum.
