4) A .2 kg meter stick at rest in outer space is hit by a .1 kg ball of clay at one end. The collision is perfectly inelastic and the clay and stick move and rotate as a single object. The initial velocity of the clay is 20 m/s in a direction perpendicular to the long axis of the stick. a) Use conservation of momentum to find the velocity of the center of mass of the stick/clay object after the collision.

4) A .2 kg meter stick at rest in outer space is hit by a .1 kg
ball of clay at one end. The collision is perfectly inelastic and
the clay and stick move and rotate as a single object. The
initial velocity of the clay is 20 m/s in a direction
perpendicular to the long axis of the stick.
a) Use conservation of momentum to find the velocity of the
center of mass of the stick/clay object after the collision.
b) Find the center of mass of the stick/clay object. It is useful
to pick an origin.
c) Find the initial angular momentum about the center of
mass.
d) Find the rotational inertia of the stick/clay object about this
center of mass.
