Chapter 12, Problem 15RE

(a)

To determine

To calculate: The acceleration as a function of $t$ where the position $s$ of a point (in feet) is given as a function of time $t$ (in seconds) as $s=\frac{2}{3t^2}-\frac{1}{t}$;$t=1$.

(b)

To determine

To calculate: The acceleration at time $t=1$ where the position $s$ of a point (in feet) is given as a function of time $t$ (in seconds) as $s=\frac{2}{3t^2}-\frac{1}{t}$.
