Question

A particle of mass 0.52 kg is attached to
the 100-cm mark of a meter stick of mass
0.21 kg. The meter stick rotates on a horizon-
tal, frictionless table with an angular speed of
1.7 rad/s.
Calculate the angular momentum of the
system when the stick is pivoted about an
axis perpendicular to the table through the
50-cm mark.

Answer 1

You need to calculate the moment of inertia for the system, bar and particle. Multiply by the angular speed to get the angular momentum.

Answer 2

0.21 kg (1.7) - (1.7) + .52 (.23)= 56degress
