Friction Force 1. A body of mass 40kg is given an acceleration of 10m/s 2 on horizontal ground for which the coefficient of friction is 0.5. Calculate the force required to accelerate the body. (Take g = 10m/s 2 ) 2. Two objects are connected by a massless string through a pulley. The mass of the two objects consecutive 5 kg and 2.5 kg. Coefficient of friction kinetics between the objects I and floor 0.2. Ignore friction rope and pulley. Find the acceleration of each objects and rope tension force that connected two object. 3. A body of mass 4kg is on the point of slipping down a plane, which is inclined at 30 o to the horizontal. What force, parallel to the plane, will just move it up the plane? (Take g = 10m/s 2 ). 4. Two beams with mass 50 kg and 100 kg are connected by a rope as a picture. Coefficient kinetic friction of 50 Kg beam with the incline is 0.25. Determine the kinetic energy change of 50 kg beam when it moves from A to B as far as 20 m. 5. A body of mas...
