so I was recently studying some ray optics and then suddenly a weird question came across my mind I just don't know if it's the correct thread to ask but let's continue anyway So the question is : suppose there is a spaceship traveling at light speed and someone fire a laser inside it what...

can we take torque around right hinge and equate it with torque of friction ? well it worked out pretty well for me.

for concurrent

I will come on thus question later first I think I need to learn more about torque so I will just brush up my theory a bit :) thank you. And I need an advice if you don't mind is reading feynman lectures nice idea prep for olympiads?

wont the direction of gravity be changing constantly?

but doing so will change the direction of gravity respect to cylinder i think.

can I take rotating frame of reference??

well I can try but scope of the problem was to teach me how to cancel out unwanted forces and torques so I think I will have to stick with torques and forces .

except from 0-45

its from projectile motion and just by changing angle its touching every part of parabola .

I thought that velocity is constant so just by changing angle we can reach any point I took help of this diagram

oops totally forgot thanks :)

is your answer √g(b+a+c) or √g(b+a-c)?? just want to confirm cause correct answer is √g(b+a+c) and I am getting √g(b+a-c)
