• Consider a ladder leaning against a wall

• Assume:
  • the ladder is rigid
  • all contact surfaces are frictionless
  • the ladder remains in contact with  the floor and the wall

• The bottom of the ladder is pulled to the right with a constant velocity VA.

• Find the velocity of the top of the ladder, VB.
