$\bullet$ $\bullet$ A harmonic oscillator is made by using a 0.600 kg frictionless block and an ideal spring of unknown force constant. The oscillator is found to have a period of 0.150 s. Find the force constant of the spring.

In physics, potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. The unit for energy in the International System of Units is the joule (J). One joule can be defined as the work required to produce one newton of force, or one newton times one metre. Potential energy is the energy of an object. It is the energy by virtue of an object's position relative to other objects. Potential energy is associated with restoring forces such as a spring or the force of gravity. The action of stretching the spring or lifting the mass is performed by a force which works against the force field of the potential. The potential energy of an object is the energy it possesses due to its position relative to other objects. It is said to be stored in the field. For example, a book lying on a table has a large amount of potential energy (it is said to be at a high potential energy) relative to the ground, which has a much lower potential energy. The book will gain potential energy if it is lifted off the table and held above the ground. The same book has less potential energy when on the ground than it did while on the table. If the book is dropped from a height, it gains kinetic energy, but loses a larger amount of potential energy, as it is now at a lower potential energy than before it was dropped.

In physics, an oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. The oscillation may be periodic or aperiodic.

So for this question, he was asking us what is a force constant. So we know the force constants able to master. Hence, the anger Frequency square. So we know any other frequencies equals the two pints has a frequency which people to find times already. We just want overtime here and from question. We know the time Here is your 0.150 2nd and the masses through on six. She was killed. So now let's figure out the angular frequency first, which is Omega equal to to buy times while over 0.150 2nd And this will give us the younger purposes for 41 point a nine radiant for a second. So if we plug it back to the OK, put em on. My God square question will get k The force constant is simply equal to mass, which is 3.600 kilograms times 41 queen a night radian per second in the whole thing square, which is equal to which will give us, uh, one point over I time tension power three Utah per meter And as the force constant bodies question Thank you
