If both of these balls are traveling down a bowling lane at the same speed, which one would would have more kinetic energy?
question 4 options:

ball a would have more kinetic energy

ball b would have more kinetic energy

both balls would have the same amount of kinetic energy since they are moving the same speed.

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,?
