Q. 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 30°, 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

Description : Neet 2015 nlm & friction q 3 As you saw ,First half of the qus was solved with Hint video Funda Kya and for the remaining half i.e coefficient of kinetic friction, i told you that we will write equation of motion as Kinetic friction is a constant force, distance is given & time is given.
