Consider three vectors: A~, B~ , and C~ . These vectors are related by: A~ + B~ = 5C~
A~ − B~ = 3C~
Vector C~ has components Cx = 2 and Cy = 4. Find the x- and y- components of A~ and B~ (e. g. find Ax, Ay, Bx, and By).

(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.)
