Q. An underwater diver sees the sun 55 degrees above horizontal. How high is the sun above the horizon to a fisherman in a boat above the diver?

Q. A .100 kg meterstick is supported at its 40.0 cm mark by a string attached to the ceiling. A .700 kg mass hangs vertically from the 5.00 cm mark. A mass is attached at another mark to keep it horizontal and in rotational and translational equilibrium. If the tension is 19.6 N determine unknown mass and the point where the mass attaches to the stick.
