AI Thread Summary
A car dealership's garage door hit a woman's vehicle while she was entering a service lane, leading to a dispute over liability. The dealership claims she was driving too fast for the door's safety features to activate, suggesting fault lies with her. The individual is seeking to calculate her speed at the time of impact to support their argument that the dealership is responsible. Key details include the garage door's height, closing speed, and the impact point on the car. The discussion highlights the complexities of liability insurance in such incidents.

My wife was pulling into a service lane at a car dealership at the same time someone inside shut the door and it hit her car. They are saying that she came into the garage to fast and the instant reverse feature did not have time to react prior to it hitting the car and therefore it was her fault. I've done an incredible amount of research and I'm very confident that this is in fact their fault, however in order to provide additional evidence I want to try and determine approximately how fast she was in fact going when the accident took place. following is the information I have.

The garage door is 15 feet high and it closes at 7 inches per second.
The impact point on her car was approximately 5 feet from the ground and the service lane is 13 yards long. I'm not sure if that is enough information to solve this equation or not. I appreciate any help you can provide.
Thank you,

This kind of stuff happens to my wife all the time. It always seems to be someone else's fault... Our wives seem to be very unlucky... Lol
 
This is a question about liability insurance, not physics.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

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...

Thread 'Newton's first law?'

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?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
