Speed of a vehicle at moment of impact

AI Thread Summary
To determine the speed required for a Toyota Avensis to move a Saab 93 estate 10 feet upon impact, various factors must be considered, including vehicle weights, passenger loads, and impact angles. The Saab weighs approximately 1,700 kg with a passenger, while the Toyota weighs around 1,510 kg with two passengers. The complexity of real-world physics, including friction and the specifics of the collision, makes it impossible to provide an accurate speed estimate without detailed accident reconstruction data. Additionally, the absence of braking and the dry conditions complicate the calculations further. Therefore, precise calculations cannot be made based solely on the information provided.

if a saab 93 estate approx weight 1600kg is hit in the passager door head on by a toyota avensis weighing 1380kg what speed does it have to be doing to move the saab 10 feet to the side.
additional weighs involved are saab plus one person 100kg
toyota additional two persons approx 130kg
dry conditions no breaking involved.
hope there are some people out there who can answer this,have to confess that electricity and everything associated with it is my bag and trying to work this out has just left me with a head ache...
thanks in advance

There are too many unknowns to get an accurate answer. We would have to reconstruct the accident from looking at the actual location, checking angles of impact, any accelerometer data, street conditions, etc. There is zero chance for a short message board post to contain enough information for even a rough estimate.
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds?

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?
