Can a Limo Fit into a Smaller Garage with Special Relativity?

AI Thread Summary
Carmen's claim that her 30 m stretch limo cannot fit into a 6 m garage is challenged by Garageman, who suggests that if the limo travels at a specific speed, it can fit. The required speed for the limo to fit is calculated to be approximately 0.9978 times the speed of light. Carmen argues that from the limo's rest frame, the garage would appear Lorentz contracted, making it impossible for the limo to fit. The discussion revolves around reconciling these conflicting perspectives using the principles of special relativity. Clarifying the proper reference frames is essential to resolving this paradox.

Homework Statement



Carmen has just purchased the world's longest stretch lim, which has proper length 30 m. A garage has a proper length of 6.0 m. Carmen concludes that there is no way to fit the limo into the garage. Her buddy Garageman claims that under the right circumstances the limo can fit into the garage with room to spare, all you have to do is speed the limo up until the moving limo takes up one third of the proper length of the garage. The front garage door closes just behind the speeding limo, and the back garage door opens just in front of the speeding limo.

1) Find the speed of the limo with respect to the garage required for this scenario.

2) Carmen protests that in the rest frame of the limo, it is the garage that is Lorentz contrated. As a result, there is no possibility whatsoever that the limo can fit into the garage. What could be the possible basis for resolving this paradox?

Homework Equations





The Attempt at a Solution



1) 2.0 m = sqrt(1-B^2)*proper length
B = .9978 c

For part 2, I am struggling to figure out which is the proper frame.

I used the Lorentz transforms for simultaneous events happening at t=0)
Event A (back of car right next to front door)
x' = 0

Event B (front of car at L/3) where L is length of garage
x' (L/3)/ sqrt(1-.9978^2) = 5.028 L

Event A
t' = 0

Event B
t' = (0-(.9978)(L/3)*(1/c^2))/sqrt(1-.9978^2) = -5.017 L/ c^2

I'm confused about what these numbers tell me. Could someone give me a push in the right direction? Thanks.

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
