Dado 𝑥 = 12𝑡^3 − 18𝑡^2 + 2𝑡 + 5, la velocidad se define como el cambio de posición a lo largo del tiempo. eso es: dx/dt. Paso 1: Resuelva la función que define la velocidad de la partícula. dx/dt = velocidad (v) = 36t^2 - 36t + 2 Paso 2: Resuelva la función que define la aceleración de la partícula. dv/dt = d^2(x)/dt^2 = aceleración (a) = 72t-36. Paso 3: Resuelva para el momento en que a = 0. a = 0 = 72t - 36 t = 1/2 segundo Paso 4. Sustituye t en las ecuaciones que definen la posición y la velocidad. x = 3 v = -7
