A student moves a 28.0 kg box of books from the faculty room to the library, which is 20 m away, the static and kinetic coefficients of friction between the box and the floor are 0.40 and 0.25 respectively. Frist, she attaches a rope forming an angle of 35º with respect to the horizontal and then she pulls it.
If she wants to move the box at a constant velocity,
If she applies a force of 105 N to he rope:
