Asked by Gabb
A block of mass 35kg 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 120N
b) the person pushes at an angle with a 25N vertical component directed down and a 200N horizontal component of the push directed forward
c)the person pulls with 120 N on a rope angle 30 degrees up from the horizontal.
