The question is in French however the translation is below

2. Evalue la vitesse et l'acceleration a # 3s pour la fonction position s(t), La distance s est en metres, et le temps t, en secondes. f(x) = ext cos( 3x + 12. Evaluates the speed and acceleration at t35 for the position function s(t). There distance s is in meters, and time t, in seconds. f(x) = e** cos3x + 1)
