In 1991, four english teenagers built an electric car that could attain a speed of 30 m/s. Suppose this car accelerates from 5 m/s to 25 m/s and travels 48 meters. What is the magnitude of the cars acceleration?

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?
