An apple breaks off from its branch and falls toward the ground 9 m below, accelerating all the way. At point S the apple is 6 m from the ground. At point T the apple is 3 m from the ground. How does the sum of the gravitational potential and kinetic energies of the apple compare between point S and point T?

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?
