suppose a pencil is balanced on a perfectly frictionless table.if it falls over, what is the path followed by the center of mass of the pencil.
Homework Answers
The centre of mass of the pencil will travel in a perfectly vertical path.
Since the friction force is non existent there will not be any force applicable on the pencil in the horizontal direction. And thus the pencil momentum in horizontal direction will remain 0.

Suppose that you are holding a pencil balanced on its point. If you release the pencil and it begins to fall, what will be the angular acceleration when it has an angle of 10.0 degrees from the vertical? A typical pencil has an average length of 15.0 cm and an average mass of 10.0g. Calculate the time for the pencil to hit the ground, assuming that it falls from standing perfectly vertical and maintains this angular acceleration.

A pencil (mass 12.0 g and length 18 cm) is initially balanced so that it is standing vertically on a flat table. If the pencil then falls, what is its angular velocity just before it strikes the tabletop? Assume the mass of the pencil is distributed uniformly and the end of the pencil in contact with the table does not slip.
