Answer (1 of 2): The answer depends somewhat on whether this is being presented as an algebraic equation, where x is a variable to be solved for, or if the equation is a formula for calculating a final velocity Vf given the initial velocity VI, an Acceleration A and a distance x. If that is the case, the formula is not dimensionally correct and thus the formula itself can not be correct. To see this, suppose the.
Dimensional Analysis: The velocity of an object is defined as the ratio between displacement and time interval. v = ?x ?t v = ? x ? t The velocity is expressed in meters over seconds, since…

4/7/2006 · (Select all that are correct .) KE = mv. 2y = (2 m)cos(kx), where k = 2 m-1. vf = vi + ax . density = volume/mass, Solution: a) vf = vi + ax Dimensions of the left hand side: vf (velocity) – L1T-1 Dimensions of the right hand side: vi (velocity) – L1T-1 a (acceleration) – L1T-2 x (displacement) – L1T0 ax – L2T-2 As the dimensions of the two terms on the right hand side are different, the equation is dimensionally incorrect.
5/6/2016 · Which of the following equations are dimensionally correct ? (a) vf = vi + ax (b) y = (2 m)cos(kx), where k = 2m^–1? Answer Save. 1 Answer. Relevance. Sqdancefan. Lv 7. 5 years ago (a) might be if the units of x are time. We usually expect t to be used for a time variable.
