Now I’m feeling good cuz I solved this in the paper… probably wasted a lot of time in the paper
But this what the paper setter’s trap…
Bcz such ques seem doable but suck lot of time…which could have been invested to do 2 - ques
Can anyone understand this question and tell me , the commas in end are confusing since its correspond to three vectors respectively.
How did you do it? I tried via contact forces between rod and block and got equation which was not proceeding further
(abx) (bcy) and (caz) are each coplanar (the three vectors in parenthesis)
Ok got it! Priniting confused me,
What about that rotation one
You did right , thats why teachers tell to leave rotation and do it at end.
Oh wait a min !! I think i got the rotation one using WPE
Yeah got it just now.
It just looked hard , was simple 2 equations.
