Hi everyone,

I am having trouble understanding this explanation at ALL. :(Cramster tries their very best, but I am just notphysics-inclined.

The book is Principles of Physics (Ch1, 7P).

Which of the following equations are dimensionally correct?

(a) Vf = Vi + ax (b) y = (2m)cos(kx), where k =2m-1.
Thanks in advance, I am just hopelessly confused about theexplanation.
