g√2/2-g/2
Component of g in direction of 45° of vertical will be gcos45. it is normal force on pulley is mgcos45 in direction of 45 with horizontal. So component of it in horizontal direction is mg(cos^2) 45. bob will only rotate . So at t=0 it's accelaration will be gcos45. So accelaration of bob w.r.t trolley will be g√2/2-g/2
