What is Max height: Definition and 124 Discussions
The Team Mini-Max Hi-MAX is a single-seat, high wing, strut-braced, single engine aircraft available in kit form for amateur construction. It first flew in 1987 and is a high wing development of the Mini-MAX, hence its model name.The Hi-MAX was originally produced by TEAM Incorporated of Bradyville, Tennessee. After that company was bankrupted by a lawsuit production passed to Ison Aircraft also of Bradyville, Tennessee and next to JDT Mini-MAX of Nappanee, Indiana. The company was renamed Team Mini-Max in 2012 and moved to Niles, Michigan.
For this problem,
The solution is,
I don't understand how they got from ##\frac {sin^2\theta_i}{sin2\theta} ## to ##\frac{tan\theta_i}{2}##. Would somebody please show me the immediate steps?
I also don't understand is why they say the ignore the trivial case where ##\theta_i = 0~rad##...
Assuming it’s one body whose initial speed is u. First it attains height h then H. t1 and t2 are two times at which they attain h and H.
##h=ut1-\frac12gt1^2##
##H=ut2-\frac12gt2^2##
##\frac {t1}{t2}=1/3## Replacing t2 with 3t1, I am stuck.
How can i find the angle that a projectile is fired where the maximun height is the same as the traveling distance?
I need to find this first in a theoretical way, then i need to confirm this with a simulation.
And i need to use only this
