Vector, scalar, scalar Scalar, vector, vector Scalar, scalar, vector Vector, scalar, vector5. An object is found to have vector components of vx = is the speed of the object? a) 259 m/s c) 22.3 m/s b) d) 13.5 m/s [N] and vy = 8.75 m/s [W]. What 10.3 m/s 16.1 m/sIs it possible to add a scalar quantity and a vector quantity? Group of answer choices No, vectors have direction and scalars do not. No, scalars have direction but vectors are just a magnitude. Yes, as long as the units are the same. Yes, but only every other Tuesday.
