A 600-kg car is going around a curve with a radius of 120 m that is banked at an angle of 25.0° with a speed of 30.0 m/s. The coefficient of static friction between the car and the road is 0.300. What is the force exerted by friction on the car?
A) 1590 N
B) 3430 N
C) 7240 N
D) 7820 N
E) 795 N

Question

Quizplus · Accepted Answer

The force exerted by friction can be calculated using the centripetal force equation and considering the banking angle. The frictional force is needed to provide the additional centripetal force required beyond what the banking angle provides.
