Question
A car is travelling at a speed of on a section of a National Highway having a downward gradient of . The driver of the car suddenly observes a stopped vehicle on the car path at a distance ahead, and applies brake. If the brake efficiency is , coefficient of friction is , driver’s reaction time is , and acceleration due to gravity is , the distance (in meters) required by the driver to bring the car to a safe stop lies in the range
Correct answer
(D) 75 to 79
Solution
To find the stopping distance, we use the formula for Stopping Sight Distance (SSD) on a gradient:Where:
- is the speed in . .
- is the reaction time .
- is the effective coefficient of friction .
- is the gradient (downward is negative) .
- is acceleration due to gravity .
