Find the right solution of following question-
Question 1- Fuzzy dice hang from the rear-view mirror of a car that is rounding a curve of radius 55 meters. If the dice are hanging at an angle of 12° from the vertical, what is the car's speed?
Question 2- If a curve with a radius of 60 meters is properly banked for a car traveling 60 km/hr, what must the coefficient of friction be for a car on the same curve traveling 90 km/hr?
I need help to solve the above question.
