part1 A 0.111 kg meterstick is supported at its
38.6 cm mark by a string attached to the ceil-
ing. A 0.689 kg mass hangs vertically from the
4.52 cm mark. A mass is attached somewhere
on the meterstick to keep it horizontal and in
both rotational and translational equilibrium.
The force applied by the string attaching the
meter stick to the ceiling is 24.8 N.
Find the value of the unknown mass. The
acceleration of gravity is 9.81 m/s2 .
Answer in units of kg.
part2 Find the point where the mass attaches to the
stick.
