he figure is an overhead view of a thin uniform rod of length
0.670 m and mass M rotating horizontally at 92.0 rad/s
counterclockwise about an axis through its center. A particle of
mass M/3.40 and traveling horizontally at speed 37.0 m/s hits
the rod and sticks. The particle's path is perpendicular to the rod
at the instant of the hit, at a distance d from the rod's
center. (a) At what value of d are rod and
particle stationary after the hit? (b) In which direction
do rod and particle rotate if d is greater than this
value?
