Greetings. I apologize in advance for not following the typical forum etiquette and introducing myself, but I have a somewhat urgent question that I need help with. I keep getting different answers and at last I find myself on freemathhelp. Below is my summary and variables:
A vehicle collides with with a wall at 25 MPH, what was the initial speed of the vehicle before braking?
Vehicle Weight - 3100 Pounds
Vehicle Drag Coefficient - .35
Braking Efficiency - 1.00
Average Skid Distance - 66.5 Feet
Estimated Speed of Collision - 25 Miles Per Hour
Drag Factor of Road Surface - .50 OR .90
If someone could help me figure out an answer using .50 and .90 for Drag Factor I would greatly appreciate it. I also hate to ask, but could someone please explain how they came up with the answer? I would like to understand everything myself so I can use this for future math problems as well.
Thank You in advance for responding.
