When you take your 1400 kg car out for a spin, you go around a corner of radius 55 m with a speed of 18 m/s. the coefficient of static friction between the car and the road is 0.88. assuming the car doesn't skid, what is the force exerted on it by static friction?

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?
