Work and Kinetic Energy - 4 Forces - Horizontal Motion This problem is similar to lecture example and discussion problem. As shown in the figure, a 23 kg block is pulled to the right by force F = 76 N. The coefficient of kinetic friction between the block and the floor is uk = 0.27. The block moves through a distance of 15.00 m. DON'T use scientific notation. Review on application of Newton's second law. Step 1: Start by drawing...
330 As shown in the figure, a 25 kg block is being pulled by a force Fup along a rough incline. The coefficient of kinetic friction between the block and the incline is uk = 0.30. Keep 2 decimal places in all answers. Step 1: Start by drawing a free body diagram of the block, including all the forces exerted on the block. Label the normal force as FN, label the weight as weight. Since the type of the frictional...

A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of p. The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an angle of 0 with the horizontal. The box was initially travelling to the right at speed v = 1.3" If M =9.7kg,...
