    Accident Auto
AI Thread Summary
The discussion centers around an auto accident involving a left turn where the driver swerved to avoid a truck, resulting in a head-on collision. The state DPS could not determine the truck's speed, prompting a question about the necessary speed for a 5,000-pound vehicle to move a 3,583-pound object 50 feet. Participants emphasized that the forum is not equipped to assist with auto accident investigations. It was recommended to hire a qualified professional auto accident investigator for accurate analysis. The conversation concluded with well wishes for the wife's recovery.

My wife was involved in an auto accident and the state DPS was unable to determine the speed of the other vehicle. The impact occurred at an intersection when my wife was making a left hand turn. In the middle of the turn is when she noticed the truck coming up the hill at her. She swerved back into her lane to avoid getting hit. At the same time the driver of the truck made a snap decision to go around her and swerved into her lane. She was then hit head on. Thanks to the safety features of her car she came out with only some cuts and bruises. Question is how fast does force A weighing 5000lbs have to go to impact object B traveling 3mph weighing 3583lbs and move it 50 feet? I know there are several other variables that will affect the outcome but this is the short and the sweet of it. I sure hope someone can help me out here. Thanks.

Welcome to PF, Tim. I'm very glad that your wife is okay -- yeah, modern safety features in cars can be amazing at saving lives.

We cannot help you with an auto accident investigation here on PF. You need to hire a qualified professional auto accident investigator for that. I have used one in the past, and they are very thorough and helpful.

Best wishes, this thread is closed.

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
