Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N. 2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
- bus weighing 500 kg on a slope that makes an angle 60 degrees with the horizontal the component of bus weight parallel to the slope is (A) 3500sqrt(3) * N (B) 1500sqrt(3) * N (C) 2500sqrt(3) * N (D) 2500N
- Find the force required to move a load of 100 N up a rough inclined plane, the force being applied parallel to the plane. The inclination of the plane is such that when the same body is kept on a perfectly smooth plane inclined at that angle, a force of 24 N applied at an inclination of 30 degree to the plane keeps the same in equilibrium. Assume coefficient of friction between the rough plane and load equal to 0.3
