Do the units in the formula below make sense, i.e., is the formula dimensionally consistent? (Here 0 is in degrees, t is in s, x is in m, vx is in ª, and ax is in ", since here we take t, x, vx, and ax to have their usual meanings for this course, for example, vx stands for the x component of velocity.) t vx Vx = 2t - tan [0] x ax ax Vx
