APFIVE Acceleration from Position Function
A particle’s position is given by $$s(t)=t^3-6*t^2+9*t+10$$. Which of the following equations correctly represents its acceleration function $$a(t)$$ (the second derivative of s(t))? (Do not use a calculator.)
A
$$a(t)=3*t^2-12*t+9$$
B
$$a(t)=6*t^2-12*t$$
C
$$a(t)=t^3-12*t+9$$
D
$$a(t)=6*t-12$$
