QuestionLe graphique v(t)v(t) d'un corps en mouvement est donné par la figure ci-dessous. The graph v(t)v(t) of a moving body is given by the figure below.
Quelle est l'accélération à linstant t=3t=3 s? What is the acceleration at time t=3 s\mathrm{t}=3 \mathrm{~s} ?
Select one or more: 4 m/s24 \mathrm{~m} / \mathrm{s}^{2} 2 m/s2-2 \mathrm{~m} / \mathrm{s}^{2} 4 m/s2-4 \mathrm{~m} / \mathrm{s}^{2} 2 m/s22 \mathrm{~m} / \mathrm{s}^{2} 0 m/s20 \mathrm{~m} / \mathrm{s}^{2}

Studdy Solution
Puisque la vitesse est constante à t=3 t = 3 secondes, l'accélération est a(3)=dvdt=0 a(3) = \frac{dv}{dt} = 0 .
La solution est:
0m/s2 \boxed{0 \, \mathrm{m/s}^2}
