Un tranvía que parte del reposo adquiere al cabo de 20 m recorridos con movimiento uniformemente acelerado, la velocidad de 36 km/h. Continúa con esa velocidad durante un minuto, al cabo del cual frena y disminuye uniformemente su velocidad hasta parar a 650 m del punto de salida. Hallar: La aceleración y el tiempo en la primera fase del movimiento. La aceleración y el tiempo en la última fase del movimiento

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?
