, m = 5 kg, and the kinetic frictional coefficient between the block and the inclined surface mu_k = 0.2
The weightless block is fixed at the top of the inclined plane, which makes an angle of 300 with the horizon. Weights 1 to 2 of the same mass of 1 kg connected by a thread and thrown over the block. Find the acceleration with which weights and the force of tension of the thread move. The friction in the block is neglected, and the coefficient of friction on the inclined plane is 0.1.
A boxweighing 150 lb is moved across a horizontal floor by dragging it means of a rope attached to the front end. If the rope makesan angle of 30 ̊with the floor and if the coefficient of friction between box and floor is 0.4, find the force exerted by the man pulling the rope.
