A rock is launched at a speed of 75 m/s from ground level, at an angle of 30° above the horizontal toward a 17.0 m high wall, which is located 30 m away does the rock clear the wall? If so, by how much? If not, at what height does it hit the wall?

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,?
