draft 2 individual work i) Using circular motion analysis, nd a value for the radius of curvature at the points 4,5,?,8,9,10,11,12, 13 to ensure that the normal force is not too big or small {4mg >FN > 0 mg). Be sure to annotate calculations and include a rationale for any assumptions you make. ii) ensure that the coaster is moving fast enough at point 8 to complete the loop iii) pick a reasonable value for the radii -give a rationale- at points 6 and 14, and then calculate the banking angle. Ensure the normal force is not too large
