Q1. The 72 m tall tower in figure below is supported by three cables that exert forces FAB, FAC, and FAD on it. The magnitude of each force is 2kN.

(a) State the total force exerted on the tower by the three cables in terms of components.

(b) Consider the tower described in (a). The magnitude of the force FAB is 2 kN. The x and z components of the vector sum of the forces exerted on the tower by the three cables are zero. What are the magnitudes of FAC and FAD?

Q2. A state highway patrol car radar unit uses a frequency of 8.00×10^9Hz. What frequency difference will the unit detect from a car receding at the speed of 44.50 from a stationary patrol car?
