In fig, a mass 5 kg slides without friction on an inclined plane making an angle 30º with the horizontal. Then the acceleration of this mass when it is moving upwards, the other mass is 10 kg. The pulleys are massless and frictionless. Take g = 10 m/sec2.-

A 100 kg box slides without acceleration down a rough inclined plane making an angle of 30^0 with the horizontal. Find it’s acceleration when the inclination of the plane is increased to 60^@ .

Find the acceleration of masses m_(1) and m_(2) moving down the smooth incline plane. The string and the pulley are masseless and frictionless.
