Physics:Rolling Motion

  1. Oct 24, 2004 #1
    A ball of radius 0.260 m rolls along a horizontal table top with a constant linear speed of 3.00 m/s. The ball rolls off the edge and falls a vertical distance of 2.30 m before hitting the floor. What is the angular displacement of the ball while it is in the air? (assume that there is no slipping of the surfaces in contact during the rolling motion.)

    What's the angular velocity of the ball? (You can calculate this, because you know its linear speed and radius).

    What is the amount of time the ball is in the air?

    Show us what you have done.

    Also note that only the vertical speed changes while the ball is falling, not the horizontal speed or angular velocity.
