Question

A) On a frictionless table, a glob of clay of mass 0.360 kg strikes a bar of mass 0.760 kg perpendicularly at a point 0.450 m from the center of the bar and sticks to it. If the bar is 1.460 m long and the clay is moving at 8.900 m/s before striking the bar, what is the final speed of the center of mass?

A) __2.8607 m/s___

B) At what angular speed does the bar/clay system rotate about its center of mass after the impact (in rad/s)?

B) _____?_____

Got the a) part but cannot get b)

How do you find b)?

Explanation / Answer

B) angular speed is w = v/r = 2.8607/(1.46/2)= 3.918 rad/sec
