A block of mass 20 kg, lying on a smooth plane inclined at 30° to the horizontal, is being pulled by a another block of mass 15 kg as shown in figure. The 15 kg block is connected to the first block by a light in extensible string and hangs freely beyond the frictionless pulley. What will be the acceleration, with which the block 15 kg comes down?(Answer up to one decimal place)
Correct answer is '1.4'. Can you explain this answer?

Let m1 = 20 kg, m2 = 15 kg and α = 30°.
Let a be the acceleration of mass m2 in downward direction, then a will be acceleration of m1 in upward direction along the plane.
All force acting on system is shown in figure.
Consider the motion of m2. Applying newton second law, we get
m2g – T = m2a …. (1)
Now consider the motion of m1. Applying newton second law, we get
T - m1 g sin α = m1 a
Adding equation (1) and (2), we get
m2g – m1g sin α = m2a + m1a
Substituting all the values, we get
