both block and wedge are of mass m . Question is to find acceleration of wedge and block .
I can understand how to solve it taking wedge as frame of reference .
but when am trying to find solution taking ground as frame of reference and finding their acceleration different .
the answer should be
acceleration of wedge =[ gsin(theta)cos(theta) ] / ( 1 + sin^2 (theta) )
acceleration of block = big one
My approach to solve it wrt ground frame of reference :
For block : gsin(theta ) is acceleration
Normal Force = mg cos (theta)
For wedge : g cos (theta ) sin (theta) = acceleration
But a should come as I said earlier . Where am I wrong ?
