Module 3 Discussion MMT

Instructor:

Each student will create a problem or experiment, illustrating one of the concepts covered in this module, and share it in your initial Discussion Board posting. A template for both of these posts can be found in my online office and course syllabus. You must make your initial 250-word post and then post a reply of at least 200 words to the initial posts of two or more of your fellow The instructor will be actively engaged and contributing to the Discussion Board activities throughout the module.  Points will be deducted for poor grammar, misspelled words, improperly cited web/textbook references, late initial posts, and posts made all at one time (do not “post and run”).  Posts made after the end of the module will be reviewed by your instructor, but you will not get any credit for them.  In addition to your individual posts, the instructor will post questions relative to the topics being covered in that Module. Each student is expected to respond to those questions in addition to the posts described above.

Students:  You will receive no points for a plagiaristic post of material and/or the majority of the post is not original work (in your own words—i.e., cut/paste content from a website or paper).

A fun question for you: According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural tendency of objects to keep on doing what they are doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion. This is often called the law of inertia. Using this information, answer the question of why motorcycles don’t have seat belts or some type of restraint system but cars do?

Think about a motorcycle hitting a 5 foot high brick wall at 60mph (about 27m/s). Let’s use a 240lb (109kg) rider as our example. Let’s assume it takes .5 seconds for the bike and rider to hit the wall. What force would the rider experience as he hit the wall?

What would happen if he hits a wooden fence and which takes much longer to slow him down (let’s say 3seconds)?

Based on your calculations, why might it be better for a motorcycle rider to not be restrained to the motorcycle he or she is riding?

Don’t spend an inordinate amount of time thinking this through. Focus on the Physics we discussed in class and give it your best shot. I’ll discuss the answer later in the week.
