1. A janitor pushes on a trashcan with a force of 47 N and 15° below horizontal axis. The trashcan is 15-kg. The static and kinetic friction coefficient between the trashcan and the ground are μs = 0.28 and μk = 0.13, respectively. N: normal force; W: weight force; f: friction force; j: janitor; t: trashcan; g: ground; E: earth. Select the correct value of normal force from the ground to the trashcan (Ngt).
