(b) (Evaluated for mathematical work accuracy and notational neatness) In our second setup, the attachments on the ceiling are set up differently, and we must adjust the angles of our cables to be 60 and 30, as shown in the gure on the left. Let F1 be the vector that represents the force on the left cable, and F2 be the vector that represents the force on the right cable. Find the vectors F1 and F2. (Hint: We will need to set up two equations to nd the magnitudes of the vectors F1 and F2. Start this problem by setting up F1 and F2 as unit vectors with the desired directions times scalars representing the unknown magnitudes. Use 9 as a parameter to represent acceleration due to gravity). W
