This is usually stated with a more reasonable precision as 3.00 × 10 8 m/s. The speed of light in a vacuum is assigned the symbol c (italic) when used in an equation and c (roman) when used as a unit. WebThe formula you listed in the first question is a derivation of the sum of areas of the rectangle and triangle. Here S is displacement, u is initial velocity, v is final velocity, A is acceleration and t is time. D = ut + (1/2) (v-u)t (Multiplying and dividing t) D = ut + (1/2) [ (v-u)/t]t.t [ (v-u)/t is Acceleration] D = ut + (1/2)A (t^2) inboard longboard
