The same explosive charge is used, so the total energy of the cannon plus cannonball system remains the same. disregarding friction, how much faster would the ball travel if the cannon were mounted rigidly and all other parameters remained the same? answer in units of m/s.

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,?
