1. ### Block on movable wedge pulley system

If to displace the wedge by lets say x meters then the string which you marked with green will displace x similarly the blue one would move x too hence total disp in x dir would be equal = 2x this would result in the increase of length in the red string as the string is inextensible..... what...
2. ### Block on movable wedge pulley system

sorry the ans should accof wedge=2acc of blockwrtwedge
3. ### Rotational: angular momentum

Thanks for the reply but I solved it

I solved it
5. ### Rotational: angular momentum

but can you please solve iit jee paper 2 2016 rbd question
6. ### Rotational: angular momentum

I solved it just used the wrong equations ...!
7. ### Rotational: angular momentum

It's not fixed ...it's on the floor free to rotate and translate
8. ### Rotational: angular momentum

Homework Statement a spool of radius R1 and R2 (R2>R1) is kept on hortizontal surface. A force f= 2t N (where t is time ) acts on the inner radius tagentially find the angular momentum of the system about the bottomost point of the spool. Homework Equations v=u+at W=Wi+alpha(t) L=IW+mvr...
