(25%) Problem 2: A conveyor belt, moving slowly at a constant speed, passes through a small window in a wall which is big enough to accommodate a single parcel, but a foolish handler stacks two parcels on the belt. The one at the bottom, parcel 1 which has mass my = 3.83 kg, continues, without slipping against the belt, through the window. (The belt continues without slowing.) The one on the the top, parcel 2 with mass my =1.22 kg, presses firmly against the wall and slips across the lower parcel. The same coefficients of friction, A, =0.51 and put =0.29, apply between the pair of parcels and between the parcel and the belt. m2 . Weights, if required, will be denoted with the corresponding subscript of the parcel as Fai, for i = 1, 2. mi . The normal force exerted by object a on object b, if required, will be denoted as Fn,a +b for a, be {1, 2, belt, wall}, but a * b. . The force of kinetic friction exerted by object a on object b, if required, will be denoted as Fha s for a, be {1, 2, belt, wall), but a # b. . The force of static friction exerted by object a on object b, if required, will be denoted as Fs,a tb for a, be {1, 2, belt, wall), but a * b.$ 20% Part (c) What is the magnitude, in newtons, of the frictional force acting on the parcel on the top, parcel 2?
