Pulley and mass

Classical Mechanics Level 3

Find the acceleration w of the body 2 in the arrangement shown in figure. if its mass is n times as great as the mass of bar 1 and the angle that the inclined plane forms with the horizontal is equal to a. The masses of the pulleys and the threads as well as friction is negligible. l is the point where string of pulley is fixed.

w=2g(2n-sin(a))/(4n+1) w=2g(4n+1)/(2n-sin(a)) w=2g(4n+1)/(2n-cos(a)) w=2g(2n-cos(a))/(4n+1)
