First, we are going to find the radius of the yaw mark. To do that we are going to use the formula:
where
is the length of the chord
is the middle ordinate
We know from our problem that the tires leave a yaw mark with a 52 foot chord and a middle ornate of 6 feet, so
and
. Lets replace those values in our formula:
Next, to find the minimum speed, we are going to use the formula:
where
is <span>drag factor
</span>
is the radius
We know form our problem that the drag factor is 0.2, so
. We also know from our previous calculation that the radius is
, so
. Lets replace those values in our formula:
mph
We can conclude that Mrs. Beluga's minimum speed before she applied the brakes was
13.34 miles per hour.
