The equation we will use is v2 = v02 + 2a (Δx). 2. Since we know the values of all variables except final velocity, we may plug in our known values and find v. v2 = (5 m/s)2 + 2 (2 m/s2) (20 meters) v2 = 105 v = 10.25 m/s 3.

Note that all of these equations [eqns. (11.2), (11.3), and (11.4)] are dimensional equations and so if quoted values are to be used for the various constants, the dimensions must be expressed in appropriate units. In Bond's equation, if L is expressed in microns, this defines E i and Bond calls this the Work Index.
