A small aircraft is headed due south with a speed of 57.7 m/s with respect to still air. Then, for 8.77 x 102 s a wind blows the plane so that it moves in a direction 36.1 ° west of south, even though the plane continues to point due south. The plane travels 88.1 km with respect to the ground in this time. Determine the velocity ((a) speed and (b) direction) of the wind with respect to the ground. Give the directional angle relative to due south.

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,?
