CPM Homework Help : CALC Problem 11-101

Multiple Choice: A particle moves on a plane curve so that at any time $t > 0$ its coordinates are given by $x = (2t − 1)^4$ , $y = t^2 + 1$ . The acceleration of the particle at $t = 1$ is:

$\langle 1,2 \rangle$

$\langle 4,2 \rangle$

$\langle 8,2 \rangle$

$\langle 24,2 \rangle$

$\langle 48,2 \rangle$

Hint:

$\vec{a}(1)=\langle{x^{\prime\prime}(t),y^{\prime\prime}(t)}\rangle\Big|_{t=1}$
