A plank with a box on it at one end is gradually raised about the other end. As the angle of inclination with the horizontal reaches 30⁰, the box starts to slip and slides 4.0 m down the plank in 4.0 s. The coefficients of static and kinetic friction between the box and the plank will be, respectively.
