constraint motion
Two blocks are moving through an L shaped passage, The block on top moves left with a velocity of 10 m/s. The bottom block is connected to an ideal string to the first block. What is the downward velocity of the bottom block? I tried using vectors, but I'm not getting the answer.

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.velocity along the string will be equal
V sin theta= 10 cos theta
Thank you so much, I found my mistake
Also, can we just move around the velocity vectors (without changing the direction)? In order to get new relations between them by known angles, It shouldn't affect our answer right?
we normally move the vectors in order to do vector addition, dot product etc, what's the need to do that here?
Suppose I want to find the magnitude of one vector along another and the angle between them is obtuse, it will be much easier to move it around, retaining the angles and then find it I think
you mean rotating the vector to make the angle accute? 💀
Not rotating, moving it
as in the first case it's not possible to drop a perpendicular from the yellow vector onto the green one
lala suno, pehle toh "angle between vectors" hamesha tail to tail join kar ke dekhte hain, toh angle obtuse tha wo obtuse hi rahega that can't change
Thanks
So for angle between vectors we keep it tail to tail, but for finding projections onto each other, it won't make it incorrect to move it around right?
...the angle between them is acute though?
In this case.
sorry, I took the opposite of the correct definition for angle between vectors
the head should be switched with the tail
yup
is this solved?
yes sir
sorry for not closing it earlier
