I’m studying for my Physics class and need an explanation.
If the vertical position of a ball as a function of time is [Image unavailable: LaTeX: y\left(t\right)=b\cdot t+c\cdot t^3\:] y ( t ) = b ⋅ t + c ⋅ t 3 where b = 2 m/s and c = -2 m/s3, what is the acceleration of this ball at the time t = 2 s?
Group of answer choices-18 m/s2
-36 m/s2
-24 m/s2
-12 m/s2
