A 0.105 kg meter stick is supported at its 40 cm mark by a string attached to the ceiling. A 0.77 kg object hangs vertically from the 6.33 cm mark. A second mass is attached at another mark to keep it horizontal and in rotational and translational equilibrium. If the tension in the string attached to the
ceiling is 21.3 N, ﬁnd the value of the second mass. The acceleration of gravity is 9.8 m/s2. Answer in units of kg
Part 2
Find the mark at which the second mass is attached. Answer in units of cm
