During the daytime, I teach first-year introductory physics to EE students at Aalto University, Finland. I love to code but unfortunately (or luckily?) can't devote much of my time for coding. For some reason, I find C to be extremely fascinating language to code in, in all of its primitiveness.

Finding the period and frequency for simple harmonic motion @JohnRennie, my bad. Of course $k$ is in units of force/length, i.e., newton / meter in the SI world. |

Finding the period and frequency for simple harmonic motion The problem setting already has all the necessary information. A 1 lb weight causes 24 in static deflection, which means that then the weight is in balance, which means...? $k$ will in units of 1/length. |

Finding the period and frequency for simple harmonic motion you should get value for $k$ from the given information of static deflection, I think. |

Finding the period and frequency for simple harmonic motion $my^{\prime\prime} + ky =0$ is your equation of interest. It's a standard 2nd order differential equation and every maths textbook involving differential equations tells you how to solve it. |

Is it possible to find out the distance traveled by a car if the force applied on it is given? @ja72, your derivation using $a(v)$ is nice and elegant! No need to go through two steps like I did, when you can get displacement directly from acceleration as a function of velocity. |
