Calculate the skid-to-stop of a car travelling oa a road at 100km/h with a coefficient of friction of 0.68.
Vf^2=Vi^2 + 2ad where a=mu*g
solve for distance d.
To calculate the skid-to-stop distance of a car, you can use the following formula:
Skid-to-Stop Distance = (Initial Velocity^2) / (2 * Coefficient of Friction * Acceleration due to Gravity)
Here's a step-by-step guide on how to calculate it:
Step 1: Convert the initial velocity from km/h to m/s.
Since the formula requires velocity in meters per second, we need to convert 100 km/h to m/s.
1 km/h = 0.2778 m/s
Therefore, 100 km/h = 100 * 0.2778 ≈ 27.78 m/s.
Step 2: Calculate the skid-to-stop distance using the formula.
Skid-to-Stop Distance = (27.78^2) / (2 * 0.68 * 9.8)
Skid-to-Stop Distance ≈ 770.33 meters
Therefore, the skid-to-stop distance of a car traveling at 100 km/h with a coefficient of friction of 0.68 is approximately 770.33 meters.
