tan() = 1/2 gives the ratio of the vertical and horizontal velocity. So use that and the previous question part

It wants d in there, so the obvious place to start is the answer to c)? Using the tan() info should give a simple
u = ... v
which will substitute in.
u = ... v
which will substitute in.
How can I substitute d into my equation for u which i posted?

Why bother? The obvious method is to start with the answer for c), which Im presuming you have.

Yeah I do. So how can I use my answer to solve the question,sorry.

Youve not posted your equation, but you want to substitute/replace U with the tan() information and rearrange to get the desired form.

No idea what you did, but you have a 2U. What can you replace/substitute that with, using the tan() information.
With u=2√v^2-2gh??

You must realise that the direction of motion (simple right triangle)
tan(theta)=1/2
means
2v=u

So i just sub u into equation for d?
Well done! You have completed 50% of the work.
----Eqn 1
----Eqn 2
Indeed, the next step is to substitute the second equation into the first equation and make V the subject.
If you can do (c), the algebraic manipulation should not be too difficult for you.
If you are stuck, post your working.
what q paper is this from?
