A 100 N box is initially at rest on a rough horizontal surface. The coefficient of static friction between the block and the surface is 0.6 and the coefficient of kinetic friction is 0.4. A man decides to move the box so he applies a steadily increasing horizontal force F_Applied on the box to the right as shown. The graph on the left below shows the horizontal force F_Applied on the box as it goes from 0 to 80 N...

A string is tied to a box that weighs 175 N. The string is angled in the direction 30.0◦ above the horizontal and used to pull the box across a rough horizontal surface with increasing speed. The tension in the string has a magnitude of 150 N and the coefficient of kinetic friction between the block and the surface is µk = 0.500. (a) Draw the free-body diagram of the box. Make sure you label all your vectors and clearly...
