Susan and jamal are playing volleyball. susan spikes the ball. when she strikes the ball with her fist, it flies into the air and over the net. eventually, it falls down and lands on the ground. jamal is unable to get to the ball in time to hit it back over the net. susan gets a point! how was susan able to overcome and work with gravity to score a point? be sure to explain the positive and negative actions taking place in this scenario.

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,?
