A block of mass m=2kg on a smooth inclined plane at an angle 30∘ is connected to a second block of mass m2=3kg by a cord passing over a frictionless pulley as shown in fig. The acceleration of each block (in m/s2) is
(assume g=10m/sec2)

Solution
NLM for m and m2 gives m2g−T=m2a.....(1) T−mgsinθ=ma.....(2)
Adding (1) and (2) m2g−mgsinθ=(m+m2)a
