 P: n/a In the equation x = vt, v is a constant. Watch this: Acceleration is constant: (1.) a(t) = a_0 Integrating, we have velocity: (2.) v(t) = a_0 * t + v_0 v_0 is the initial velocity. Integrating again, we have position: (3.) s(t) = (a_0/2) * t^2 + v_0 * t + s_0 s_0 is the initial position. Note, if we let a_0 = 0, s_0 = 0, (3.) becomes this familiar expression: (4.) s(t) = v_0 * t This naturally implies that v(t) = v_0. One needs to distinguish between constants, various types of functions, and dependent and independent variables.
