Ahoop (i = mr2) of mass 3 kg and radius 1.1 m is rolling at a center-of-mass speed of 11 m/s. an external force does 842 j of work on the hoop. what is the new speed of the center of mass of the hoop (in m/s)? round your answer to the nearest whole number.

Explanation:

Since the hoop is rolling on the floor so its total kinetic energy is given as

now for pure rolling condition we will have

also we have

now we will have

now by work energy theorem we can say

now solve for final speed

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."
