$\mathrm{s}$ Is the Distance (In $\mathrm{ft}$ ) Traveled in Time $\mathrm{t}$ (In S) by a Particle

Multiple Choice

$\mathrm{s}$ is the distance (in $\mathrm{ft}$ ) traveled in time $\mathrm{t}$ (in s) by a particle. Find the velocity and acceleration at the given time.
- $s=-5 t^{3}+3 t^{2}-5 t-4, t=2$

A) $v=-8 \mathrm{ft} / \mathrm{s}, a=-53 \mathrm{ft} / \mathrm{s}^{2}$
B) $v=-53 \mathrm{ft} / \mathrm{s}, \mathrm{a}=-54 \mathrm{ft} / \mathrm{s}^{2}$
C) $v=-54 \mathrm{ft} / \mathrm{s}, a=-53 \mathrm{ft} / \mathrm{s}^{2}$
D) $v=-53 \mathrm{ft} / \mathrm{s}, a=-8 \mathrm{ft} / \mathrm{s}^{2}$
