A person stands at the base of a hill that is a straight incline making an angle x with the horizontal. For a given initial speed v, at what angle y (to the horizontal) should objects be thrown so that the distance d they land up the hill is as large as possible?(adsbygoogle = window.adsbygoogle || []).push({});

I realise that tan x = vertical displacement/horizontal displacement, and d^2=horizontal distance^2+vertical distance^2. But no matter how do I manipulate the equation, it seems that I can't get rid of the variable t. Any help would be aprreciated.
