Homework Help: Angular displacement

  1. Mar 5, 2006 #1

    how do i work out the angular displacement of ball bearing 0.00765 m in radius over 0.05 meters?

    i need it to work out angular speed.

    thank you

    Perhaps you need:

    [tex]d = \theta r[/tex]

    [tex]v = \omega r[/tex]

    Where the angle is measured in radians.

    im doing this piece of work about a ball bearing rolling down an invlined slope and translational kinetic energy + rotational kinetic energy should = potential enegry.

    but im not sure how to work out rotational kinetic energy. im not sure of the equations you just gave me, sorry, a little more help maybe?

    can i not just say that the angular displacement is 0.05 meters? as that is how much we moved the ball bearing back each time?

    thank you, but could i please have a little more help?
