Fundamentals of Differential Equations

A $$1 / 8-\mathrm{kg}$$ mass is attached to a spring with stiffness 16 N/m. The damping constant for the system is 2 N-sec/m. If the mass is moved $$3 / 4 \mathrm{m}$$ to the left of equilibrium and
given an initial leftward velocity of 2 m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency.

Use the following information to answer the next seven exercise. Four basketball teams took a random sample of players regarding how high each player can jump (in inches). The results are shown in Table 13.15.
$$ \begin{array}{|l|l|l|l|}\hline \text { Team } & {1} & {\text { Team } 2} & {\text { Team } 3} & {\text { Team } 4} & {\text { Team } 5} \\ \hline 36 & {32} & {48} & {38} & {41} \\ \hline 42 & {35} & {50} & {44} & {39} \\ \hline 51 & {38} & {39} & {46} & {40} \\ \hline\end{array} $$
