    Estimate the initial velocity of the cars after the collision

    The speeds of the piece and car. Of course I'm not sure. I do not know the reason. Because the car stops after the collision and on the other hand the piece is with it, so I thought the speed of the piece would also decrease. I think he saw pieces of the car body scattered over a long...

    Estimate the initial velocity of the cars after the collision

    My first reason was that they should not be too different. Because they both have the same velocity relative to the ground before the cars collide. But the car velocity immediately goes to zero after the collision. The piece also slows down immediately. Because its velocity was the same as the...

    Estimate the initial velocity of the cars after the collision

    I do not think that the velocity of the piece is faster than the velocity of the car. When two cars collide, a lot of energy is released. the energy is spent separating this piece from the car. Because this piece was part of the car before the collision. For example, it was part of the car body...

    Estimate the initial velocity of the cars after the collision

    The piece has zero velocity relative to the car. But it has a velocity relative to the ground. A velocity equal to the velocity of a car. s I think there should not be much difference between the velocity of the piece at the moment of loosening and the velocity of the car. That's why I think the...

    Estimate the initial velocity of the cars after the collision

    Yes, you are right. But I really do not know. I can not find a physical reason.

    Estimate the initial velocity of the cars after the collision

    I think just having the velocity of a car is not enough. But I feel the velocity of the piece is lower than the velocity of the car.

    Estimate the initial velocity of the cars after the collision

    Do you mean to consider a range for the initial velocity of the car? But the only formula available is the piece velocity formula after the collision. I do not think that way we can consider a range for the initial velocity of the car. I do not know.

    Estimate the initial velocity of the cars after the collision

    I found the desired relationship. For the initial velocity of the piece. But I still do not know what to do with this relationship. How do I estimate the initial velocity of the car?

    Estimate the initial velocity of the cars after the collision

    I realized. So in conclusion: I have to find a relationship between the range and the height of the piece and its velocity. And then estimate the initial velocity of the car using the law of conservation.

    Estimate the initial velocity of the cars after the collision

    My goal in the range formula was to find the velocity of the piece. So when the velocity of the piece is the same as the velocity of the car, what is the need for a range! Is the idea of using the law of conservation in the way I said above correct?

    Estimate the initial velocity of the cars after the collision

    Why is the initial horizontal velocity of the piece the same as the velocity of the car? Does this mean that we have a free fall problem if the initial vertical velocity is zero?

    Estimate the initial velocity of the cars after the collision

    You are right. I realized. I'm trying to find a new formula. Although I do not know how, now. But I try. Thanks for your guidance.

    Estimate the initial velocity of the cars after the collision

    The reason the masses are unknown is that it is an analytical question. Of course, at the end we are asked to give a numerical example. I considered the angle myself and the question did not say anything about it. Because I wanted to use the range formula, I had to consider the angle as well. I...

    Estimate the initial velocity of the cars after the collision

    What came to my mind for this question is: Consider one of the cars. The velocity and mass of this car are V and M respectively. And the velocity and mass of the piece attached to the car are m, v respectively. Before the collision, the velocity of this piece relative to this car is zero. So its...

    The motion of a charged particle in a magnetic field

    hi. Thanks for your explanation. Yes, so the required radius is in CGS and not SI. Of course, unfortunately, the question did not say anything about this. So I just have to write the Lorentz force in CGS and then I get the result. yes?
