A block of mass 35 kg is on a flat floor with a static friction coefficient of 0.36 and a kinetic friction coefficient of 0.29. A person attempts to slide the box from rest in a forward direction. Find the maximum frictional force experienced and the acceleration of the box once it is moving if: a) the person pushes horizontally with 120 N. b) the person pushes at an angle with a 25 N vertical component directed down and a 200 N horizontal component of the push directed forward. c) the person pulls with 120 N on a rope up angled 30° up from the horizontal.
