Basically I am stuck... been pulling my hair out trying to simplify this and come out with a simple expression!
Also not sure what area of the forum to put this in, but seeing as there is nothing too complicated and its all algebra i think this is the right place.
Heres the problem:
Two balls are thrown at angles , , at velocity one after the other such that they collide at point B in mid air, determine the time between the throws (analytically).
Heres what i have done so far:
Resolving horizontally gives:
Resolving Vertically gives:
Sub in the expression for to find the eqn in terms of then my plan is to simplify and do the same for until finally i can do:
where is the answer to the problem.
Okay, so heres where i am stuck:
Trying to simplify the eqn. for , im not sure exactly how to do this:
I have a similar expression for .
How do i simplify that?
EDIT: I am guessing there is a trig identity for bottom part which can be written:
but i cant remember it!
EDIT 2: Perhaps there isnt, so i tried simplifying and got this:
Is that okay?
