Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.ac - r alpha = -a1 in direction
can you explain how you got that
In the question I believe they're assuming the block's acceleration to be upward
In general, when you pull the block it should go up
and the thread in the spool should get unrolled
Hence r alpha and ac are assumed to be downward while a1 is assumed to be upward
oh
alright understood
thanks a lot
