Question

Calculate the minimum distance required for a 1600 kg car to stop if its initial speed is 60 km/h, and the coefficient of friction between the tires and the pavement is 0.7.

A) 180 meters
B) 190 meters
C) 200 meters
D) 210 meters

Answer 1

The minimum distance required for the car to stop is 190 meters.

Step-by-step explanation:

To calculate the minimum distance required for the car to stop, we need to use the equation:

d = (v^2) / (2 * μ * g)

Where d is the distance, v is the initial speed, μ is the coefficient of friction, and g is the acceleration due to gravity.

Plugging in the values, we get:

d = (60^2) / (2 * 0.7 * 9.8) = 190 meters

Therefore, the minimum distance required for the car to stop is 190 meters.
