You gave a friend an outrageously large birthday present of mass m=29.7 kg. They are excitedly holding it using both hands on opposite sides of the box. Each hand applies a normal force of equal magnitude to each side of the box. The coefficients of static and kinetic friction between their hands and the paper are μS = 0.61 and μK = 0.23, respectively. The box is on the verge of slipping but they just manage to hold it. BR HAND y HAND X What is the magnitude of the normal force applied by EACH of their hands to the box? Provide your answer in Newtons to one decimal place.
