Find the angle for which a projectile fired from a height h with velicity u at an angle theta will have max. range

Question

experimentx · Answer

0 of course ... to have max range you need to have max horizontal component ... vertical component to initial velocity will only make fall faster

anonymous · Answer

0 is wrong. Give me a minute to elaborate.

experimentx · Answer

what do you mean ... when fired from HEIGHT???

anonymous · Answer

It is fired for a height h upward with an angle theta

experimentx · Answer

than that would be 45

anonymous · Answer

Yeah and now we are firing from a height h

anonymous · Answer

it would be different because the y component would be zero later than when fired from ground

anonymous · Answer

Didn't see it was launched from a different height.

anonymous · Answer

Yeah that's what makes the difference
