Explanation / Answer

1) Orange mass will have greater acceleration

2) there is only one tension acting on orange mass rather than blue mass

3) downward

4) Downward

5) upward

6)upward

7) let's write equation for both masses

M1 (a) = M1g - 2T--eq(1)

M2(a) = T- M2g ----eq(2)

multiply eq(2) by 2

2M2a = 2T - 2m2g--eq(3)

add eq( 1) and eq(3)

M1 (a) + 2M2a = M1g - 2T + 2T - 2m2g

a ( M1+2m2) = g( M1-2m2)

a= g ( M1-M2) / (M1+2m2) = 9.8 (130 )/ (200 + 140)= 3.747 m/s^2
