WHAT HAPPENS TO FRICTION AND NORMAL FORCE IF VELOCITY IS GREATER THAN V1 15. A car is navigating a banked turn. As shown below, the road surface is tilted at an angle θ from the horizontal; the car's path is a portion of a horizontal circle.**Diagrams Description:**- **Overhead View:** Shows a car navigating a curved path with velocity \( v \) and radius \( R \).- **From Behind Car:** Illustrates the car on a banked surface, angled at \( θ \).If the car's speed is \( v_1 \), the car can navigate a turn with radius \( R \) without requiring friction to keep it from slipping; at this speed, the normal force acting on the car has a magnitude of \( n_1 \). If the car's speed is smaller than \( v_1 \) and it navigates the turn with radius \( R \) without slipping, the friction force acting on the car ___ and the normal force ___.(Choose the answer that best fills in both blanks; hint: consider the case in which the new speed is much smaller than \( v_1 \).)A) has a magnitude of zero ... is smaller than \( n_1 \)B) is directed down the slope ... is larger than \( n_1 \)C) is directed up the slope ... is larger than \( n_1 \)D) is directed up the slope ... is smaller than \( n_1 \)E) is directed down the slope ... is smaller than \( n_1 \)**Correct Answer:**D) is directed up the slope ... is smaller than \( n_1 \)**Explanation:**- The car would tend to slide down, so the friction force \( f \) is up the slope.

We are given case of banking of road. The car travels with given speed in a circle. We draw free…
