Task 2

Suppose a car left a skid mark of d feet long. The above formulas will estimate the speed s in miles per hour at which the car was traveling when the brakes were applied.

 1Complete the table



  

 Why do you think the estimates of speed do not double when the skid marks double in length

 Because a car on a wet road will slide further than a car on a dry road.

 Because of the use of friction brakes and wheels on the street.

 Based on these results, what conclusions can you make about a safe following distance

 Driving on the appropriate speed and distance to stop and not be surprised, That will avoid accidents.

 when the car is driven on a wet road and not on a dry road it double the speed and you will not stop at the same time u try to stop the car
