Solve the each parts of given question:
Question: An indoor track is to be designed such that each end is a banked semi-circle with a radius of 28 m.
Part A: What should the banking angle be for a person running at speed v=6.4 m/s?
Part B: Determine the minimum angle at which a roadbed should be banked so that a car traveling at 20.0 m/s can safely negotiate the curve if the radius of the curve is 2.00 x 102 m.
Part C: What is the magnitude of the gravitational force acting on a 79.5-kg student due to a 58.0-kg student sitting 24.0 m away in the classroom?
Explanation and formulas needed for best answer! Thanks.
