Solve the all parts of following question:
Question: One stretch of I-90 near CSU was designed by someone who did not pay attention in Physics class. Normally, highway curves are banked (tilted) to allow traffic to maintain normal speed through the turn. "Dead man's Curve" has no bank.
Part A: Draw the free body diagrams of a car on a banked and non-banked turn?
Part B: Obtain a formula for the maximum speed of the car for both the banked and unbanked turn?
Part C: Using the formulas, show why highway turns should be banked?
I need help to obtain a formula for the maximum speed of the car.
