You are designing a new flat round track for go-carting. The wheels and the track have a coefficient of static friction of 0.55. These go-carts have a maximum speed of 11 m/s around turns. What is the minimum radius that the turns on the track need to be so that the cart does not slide/drift when going at maximum speed? (You must draw a free-body diagram from behind the cart and start with formulae from the formula sheet. Using memorized final equations will not be adequate for full marks.)
When the current in a toroidal solenoid is changing at a rate of 0.0260 A/s, the magnitude of the induced emf is 12.6 mV. When the current equals 1.40 A, the average flux during each turn of the solenoid is 0.00285 Wb. How many turns does the solenoi..
