Minimum distance between two perpendicular moving vehicles

AI Thread Summary
The discussion revolves around determining the minimum distance between two perpendicular moving vehicles. A proposed solution is shared, though its correctness is uncertain. The relevance of limits as vehicle speeds approach zero is acknowledged, suggesting that the question may have a deeper implication. Participants agree that a literal interpretation of the question yields an obvious answer, but there is skepticism about whether that is the intended solution. The conversation emphasizes the need for clarity in understanding the problem's requirements.

What is the minimum distance between two vehicles moving perpendicularly toward each other?
Relevant Equations
d = vt
Below is my solution, which I'm not sure is correct. Hopefully the picture shows clearly what I'm trying to find.

Looks good to me. You can also see that the limits ## v_1\rightarrow 0 ## and ## v_2\rightarrow 0 ## make sense.
 
If you read the question literally, the answer is obvious. But I don't think that's the answer they're looking for.

Hint:

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
