La trayectoria de un cuerpo en movimiento rectilíneo está determinada por: s = 115t + 12t^3 en metros y segundos. Determina la aceleración del cuerpo a los 12 segundos de origen.

a = 864 m/s^2

Step-by-step explanation:

You have the following equation for the motion of a body:

The acceleration of the body is given by the second derivative of s(t):

After t = 12 s you obtain for the acceleration:

hence, the acceleration is 864m/s^2 for t=12s
