Plss help me with 2nd question

Dear student,

L e t A = a c c e l e r a t i o n o f b l o c k M_{2} a n d p u l l e y . a = a c c e l e r a t i o n o f M_{1} L e t x d i s p l a c e m e n t M_{1}, X d i s p l a c e m e n t o f M_{2} ​ a n d p u l l e y a s s h o w n . L e n g t h o f s t r i n g p a s \sin g o v e r t h e p u l l e y i s : L = X + X - x \Rightarrow L = 2 X - x D i f f e r e n t i a t i n g t w i c e w i t h r e s p e c t t o t i m e, (a s a = \frac{d^{2} x}{d t^{2}}) 0 = 2 A - a \Rightarrow a = 2 A . . . . . . (1) T_{1} = M_{1} \times a = 0.3 a . . . . . (2) a n d 2 T_{1} ​ + M_{2} \times A = F . . . . . .
