Answer:
L = s^2/(30.25Cd)
Step-by-step explanation:
In accident investigation, the speed of a vehicle can be estimated using a polynomial function that relates speed (s) to the length of skid marks (L). The drag coefficient Cd will depend on the condition of the road surface and tires, but might be expected to be between 0.7 and 0.8.
If the skid marks end in a collision, the length of the marks that might have been made can be estimated using this formula, then that length added to the actual length of marks to estimate the original speed. The speed at the point of collision can be estimated by the damage caused, and/or the movement created.
In the above formula, length is in feet, and speed is in miles per hour.
2.603 -> 2.63 -> 2.6312 -> 2.9
It will take Ralph 5 hours to run 15 miles at a rate of 3/mph
Answer:
1342 feet
Step-by-step explanation:
The first thing we have to do is to measure your weight
using a weighing scale.
Suppose your weight is 130 pounds, therefore you can lift:
<span>130 pounds * 1.182 • 10^3 = = 153,660 pounds or 1.537 x
10^5 pounds</span>
