As part of an outdoor display, a 5-kg model c of the earth is attached to wires ac and bc and revolves at a constant speed v in the horizontal circle shown. determine the range of the allowable values of v if both wires are to remain taut and if the tension in either of the wires is not to exceed 116 n. given: r = 0.905 m.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
