A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank He places the box on the plank and gradually raises the plank When the angle of inclination with the horizontal reaches 30 the block starts to slip and slides 4 0 m down s 10 the plank in 4 0 s If is given by then B find the value of u u are coefficient of static friction kinetic friction
