Problem 1: Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the surface of the door. C pushes with a force of 18 N at a distance of 0.59 m from the hinges, and the second child pushes at a distance of 0.455 m. What is the magnitude of the force, in newtons, the second child must exert to keep the door from moving? Assume friction is negligible. F2 =

m, m2 Two wooden crates rest on top of one another. The smaller top crate has a mass of m, = 18 kg and the larger bottom crate has a mass of m2 = 85 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is µ; = 0.82 and the coefficient of kinetic friction between the two crates is Hk = 0.66. A massless rope is attached to the lower crate to pull it horizontally to the right (which should be considered the positive direction for this problem). 1) The rope is pulled with a tension T = 398 N (which is small enough that the top crate will not slide).
