An airplane flies 200 km due west from city a to city b and then 275 km in the direction of 26.0° north of west from city b to city c. (a) in straight-line distance, how far is city c from city a?
relative to city a, in what direction is city c?
(c) why is the answer only approximately correct?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
