Two blocks connected by an in-extensible string passing over a light frictionless pulley are resting on two smooth inclined planes as shown in diagram. Determine the acceleration of the blocks & tension in the string. Assume string to be massless .
Acceleration = a = g (m1sin alpha - m2sin beta) / (m1+m2)
a = 10 ( 55 x sin30 - 35 x sin60 ) / ( 55+35 )
a = 10 ( 55/2 - 35root3/2 ) / (90 )
a = 10 ( 55/2 - 60.62/2 ) / (90)
a = 10 ( -5.62/2 ) / (90)
a = -2.81/9 = - 0.31 m/s.
Hope it helps ...
