Problem 32PE
Unreasonable Results
(a) Calculate the minimum coefficient of friction needed for a car to negotiate an unbanked 50.0 m radius curve at 30.0 m/ s.
(b) What is unreasonable about the result?
(c) Which premises are unreasonable or inconsistent?
ANSWER:
Part (a)
Step 1 of 4:
A car is traveling on an unbanked curve with a particular speed and radius of the curve is given. We are going to find the coefficient of friction to negotiate the unbanked curve.
The radius of the curve
The speed of the car
The acceleration due to gravity
