A 3 kg textbook is forced against a horizontal spring of negligible mass andforce constant of 230 N/s, compressing the spring by 0.25 m. When released, the textbook slides on a horizontal tabletop with coefficient of kinetic friction0.35. Use the work-energy theorem to find how far the textbook moves from itsinitial position before coming to rest.

answer; /// the above statement is (true);

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
