What is Confusing: Definition and 407 Discussions

In medicine, confusion is the quality or state of being bewildered or unclear. The term "acute mental confusion" is often used interchangeably with delirium in the International Statistical Classification of Diseases and Related Health Problems and the Medical Subject Headings publications to describe the pathology. These refer to the loss of orientation, or the ability to place oneself correctly in the world by time, location and personal identity. Mental confusion is sometimes accompanied by disordered consciousness (the loss of linear thinking) and memory loss (the inability to correctly recall previous events or learn new material). The term is from Latin: confusĭo, -ōnis, from confundere: "to pour together", "to mingle together", "to confuse".

    Physics Confusion: The Ball's Trajectory in an Upward Throw Explained

    Say there's a ball being thrown upwards (from the bottom to the top of a building) with an initial speed of 29.4 m/s for 4 seconds at an acceleration of -9.8 m/s². Now here's a few of my problems: 1.) My book says the ball would stop after 3 seconds. Wouldn't it therefore be pointless to...

    Solve Train Speed from Frequency: 440Hz & 410Hz

    As a train APPROACHES a ringing crossing gate, Stacy, a passenger on the train, hears a frequency of 440 Hz from the bell. As the train RECEDES , she hears a frequency of 410 Hz. How fast is the train traveling? (formula: f = fo (v+ vo)/(v-vs)) f= frequency that she hears fo= actual...

    How far does the train travel during its acceleration phase?

    A train starts from rest and accelerates uniformly in a straight line until, after 10s, it attains a speed of 40m/s. It then continues to accelerate at the same rate until it has traveled a total distance of 500m. What is the distance travled by the train during the first 10s? What...
