1. A vehicle is moving at a speed of 54 km per hour. What will be the Lag Distance if the driver of the vehicle is very alert? 2. A vehicle is moving at a speed of 72 km per hour. What will be the Lag Distance if the driver of the vehicle is alert? 3. A vehicle is moving at a speed of 90 km per hour. What will be the Lag Distance if the driver of the vehicle is NOT alert? 4. Calculate the Braking Distance on a level road stretch for design speed of 54 km per hour. Assume coefficient of longitudinal friction as 0.37 and reaction time of driver is 2.5s. 5. Calculate the Braking Distance on a level road stretch for design speed of 54 km per hour. Assume coefficient of longitudinal friction as 0.77 with a brake efficiency of 60% and reaction time of driver is 2.5s. 6. Calculate the Braking Distance on a level road stretch for design speed of 108 km per hour. Assume coefficient of longitudinal friction as 0.78 with a brake efficiency of 62% and reaction time of driver is 2.2s. 7. Calculate the Braking Distance on a road stretch with descending gradient of 3% for design speed of 108 km per hour. Assume coefficient of longitudinal friction as 0.378 and reaction time of driver is 2.2s. 8. Calculate the Braking Distance on a road stretch with ascending gradient of 3% for design speed of 108 km per hour.
