A line rotates in a horizontal plane according to the equation theta=2t^3 -6t,where theta is the angular position of the rotating line, in radians ,and t is the time,in seconds. Determine the angular acceleration when t=2sec.

D.) 24 radians per sec^2 << my choice.

• Calculus (fixed the typo ) -

θ=2t^3-6t

θ'=dθ/dt=6t²-6

θ"=d²θ/dt²
=12t
