In the figure, a solid 0.3 kg ball rolls smoothly from rest (starting at height H = 5.6 m) until it leaves the horizontal section at the end of the track, at height h = 1.5 m. How far horizontally from point A does the ball hit the floor?

In the figure, water (density = 1.0 x 103 kg/m3) flows through a horizontal pipe and then out into the atmosphere at a speed v1 = 14.0 m/s. The diameters of the left and right sections of the pipe are 5.20 cm and 3.20 cm. Find the speed v2 .

The vessels shown below all contain water to the same height. Rank them according to the pressure exerted by the water on the vessel bottoms, least to greatest.

Find the escape speed on a spherical asteroid whose radius is 927 km and whose gravitational acceleration at the surface is 0.958 m/s2.  Then calculate how far  (in km) from the surface will a particle go if it leaves the asteroid’s surface with a radial speed of 877 m/s? (Enter the distance in km.)

A flywheel turns through 20 rev as it slows from an angular speed of 9.0 rad/s to a stop.  What is its angular acceleration (magnitude)? 

Spend 10-12 minutes on this question. Your grade on this ‘summary of our semester’ question is based on providing a complete answer, that will be two paragraphs of 5 to 8 sentences for each paragraph, responding to the following scenario and application. The question has you applying theories we’ve covered to a topic related to assessing your personal growth in the course. First, here’s a foundation for our class: Through effort on your part, you should have a new range of knowledge that has a good chance of being useful to you, likely in another class, likely in your career. Part of making it through a class is–for some students, but not all–to see that you may be accustomed to classes that don’t expect much of you. Classes may have minimal assigned work, and minimal work expectations. (Some of you acknowledged this reality in your final Reflections answers.) Other teachers / professors may use a different approach that also works to help you learn. But, the process of learning is why we should be here, and I believe it’s not in your best interest to instead let you ‘bluff your way through.’ I can also see the over-dependence on AI from a lot of you, instead of people making their own effort (yes, it’s obvious). As I have said, you’re just cheating yourself. So from this described environment, some of you have a completely different mindset than I have about what a university class should be. I accept that some students will be upset that they are pushed to work harder than they’re expecting. I have spent my entire life living the adventure of being fully engaged as ‘a media person.’ It doesn’t mean I’m always great at everything I do, but it does mean I always try to be as good as my abilities allow, and to keep learning. I have also had some important mentors. So, from that described context, now apply something you have learned in this class. We used the term hegemony throughout the semester, meaning ‘negotiating a preferred position.’ Here’s our first scenario: some students’ preferred position may be “don’t challenge me to think more deeply, don’t ask much work from me” while my position is “my job is to push you to see your potential, trying to serve as a caring mentor, trying to guide you toward making yourself competitive from your skills and knowledge for when you’re getting into a career. Second scenario:  “Spiral of Silence” means a person who sees themselves as being in the minority against a majority opinion and may choose to stay silent instead of speaking up. Within that model, I choose NOT to stay silent, but to ‘speak up’ by trying to push back against an expectation that a university class should expect very little of you, and in turn provide very little educational growth for you. Now to the writing about these: Your 1st paragraph: say how you agree or disagree by applying hegemony and describing ways it works to the challenge for college students related to any class they may take. Your 2nd discussion paragraph: apply Spiral of Silence to say how you agree or disagree with someone seeing the better potential possible in college students and speaking up and pushing back against a system that doesn’t work to help each person achieve their full potential and describing ways it works to the challenge for college students related to any class they may take.

A disk, initially rotating at 118 rad/s, is slowed down with a constant angular acceleration of magnitude 3.59 rad/s2. How much time does the disk take to stop?

A 4-kg block, attached to a spring, executes simple harmonic motion according to x = 2cos(40t) where x is in meters and t is in seconds. The spring constant of the spring is:
