Arock is thrown upward from level ground in such a way that the maximumheight of its flight is equal to its horizontal ranger. a) at what angleθis therock thrown? b) in terms of its original ranger, what is the rangermaxtherock can attain if it is launched at the same speed but at the optimal anglefor maximum range? c) would your answer to part a) be different if the rockis thrown with the same speed on a different planet? explain.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
