QuestionFind the car's acceleration at $t=2$ seconds given $s(t)=2 t^{4}-10 t^{3}-5 t^{2}+9$. Answer in $\mathrm{m} / \mathrm{s}^{2}$.

Studdy Solution
Calculate the acceleration at $t=2$ seconds.
$$a(2) =24(4) -60(2) - =96 -120 - = -34 \, \mathrm{m/s}^{2}$$The acceleration of the car at $t=2$ seconds is $-34 \, \mathrm{m/s}^{2}$.
