## Calculus: Early Transcendentals 8th Edition

a. $6 \frac{kg}{m}$ b. $12 \frac{kg}{m}$ c. $18 \frac{kg}{m}$ The highest is when $p(3) = 18$ and the lowest one is when $p(1) = 6$.
a. $1m$ $m = 3x^{2}$ $p = \frac{d(3x^{2})}{dx}$ $p = 6x$ $p(1) = 6(1)$ $p(1) = 6\frac{kg}{m}$ b. $2m$ $m = 3x^{2}$ $p = \frac{d(3x^{2})}{dx}$ $p = 6x$ $p(2) = 6(2)$ $p(2) = 12\frac{kg}{m}$ b. $3m$ $m = 3x^{2}$ $p = \frac{d(3x^{2})}{dx}$ $p = 6x$ $p(2) = 6(3)$ $p(3) = 18\frac{kg}{m}$
