A car traveled from Toronto 300 km[S] , then went 200 km [N], finally the car went Went 400 km[S] if the total time is 10 hours, Calculate:
1. The car’s total displacement relative to Toronto using diagram only.
2. The car’s average velocity.

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,?
