An 82 Newton trunk is accelerating along a plank inclined at 26 degrees from the horizontal. The coefficient of kinetic friction of the trunk and plank is .20
What is the value of F sub g
the value of f sub g of x
the value of f sub g of y
the value of the normal force
the value of friction
the value of the net force
What will happen to the acceleration of the trunk if the elevated end of the plank is raised? Why?
What will happen to the motion of the trunk if it reaches a section of the plank where the coefficient of sliding friction makes the frictional force equal to the magnitude of the horizontal component of the weight force?
