Question

it is found that,id a street surface is dry,a good driver can safely decelerate an automobile with reasonably good tires at the rate of about 4.57m/s² so,forms a car movings at 60km/hr what should bear the minimum distance between two cars so that the work crash during sudden stop

Answer 1

To find the minimum distance between two cars during a sudden stop, we can use the formula for stopping distance. Using the given deceleration rate and initial velocity, we can calculate the minimum distance.

Step-by-step explanation:

To find the minimum distance between two cars to avoid a crash during a sudden stop, we need to calculate the stopping distance of the car. Given that a good driver can safely decelerate a car at a rate of 4.57 m/s² on a dry surface, we can use the formula:

Stopping distance = (Initial velocity²) / (2 * deceleration)

Converting the initial velocity from 60 km/h to m/s (16.67 m/s), we can substitute the values into the formula:

Stopping distance = (16.67 m/s)² / (2 * 4.57 m/s²)

Calculating the stopping distance will give us the minimum distance between two cars to avoid a crash during a sudden stop.
