Due Date/Time: 10:35 AM Wednesday February 5, 2025.  Maximum Time Limit = 65 Minutes (in one sitting).  Must be taken in one 65-minute sitting/session.  IF YOU NEED TO USE SCRAP PAPER, ASK FOR SOME.   Be sure that you type all your answers and any work into the exam, too, please.   IF YOU NEED TO USE A CALCULATOR, IT MUST BE A REGULAR CALCULATOR (HAND-HELD).  PHONES AREN’T PERMITTED.   REMINDERS: Exams, tests, and quizzes are closed books, closed notes, closed slides, closed assignments, and taken individually.  No additional devices allowed other than the one (1) being used for the exam/test/quiz. Only the test/exam/quiz screen should be open.  A simple, basic calculator can be used (not phones).  No other windows, websites, programs are permitted. 

Match the process with its descriptions/components.

Why would stroke volume increase if the heart rate slows down?  Explain in 1-3 sentences, please.

A wheel is pivoted at its center. It has a radius R and mass M. A piece of clay of mass m and speed v is about to strike it at the bottom edge, tangentially, as shown, and sticks to it. What is the angular velocity of the system right after the collision?                                                      

A ball is launched from the top of a building that is 20 meters tall with an initial speed v0= 30 m/s{“version”:”1.1″,”math”:”v0= 30 m/s”} and at a non-zero angle θ{“version”:”1.1″,”math”:”θ”} below the horizontal. If y=0 at the ground, what is the correct equation for y as a function of time?

If you know two vectors’ components, A → = ( A x , A y , A z ) ,  and  B → = ( B x , B y , B z ) , {“version”:”1.1″,”math”:”\vec{A}=(A_x,A_y,A_z), \mbox{ and } \vec{B}=(B_x,B_y,B_z), “}how can you determine whether these vectors are perpendicular to each other?

Please draw the standard xy coordinate system on a paper sheet. This paper sheet lies on a table. A little alien visits from outer space, takes out a little bicycle, and rides on the sheet along the x-axis in its positive direction at constant velocity. What is the direction of the angular momentum of a bicycle wheel?

Find the angle between vectors F = (3, 0, 4) and d = (1, -2, 2).

A body of mass 10 kg is initially at rest on a horizontal surface. The coefficient of static friction between the body and the surface is 0.7, and the coefficient of kinetic friction is 0.4. A horizontal force 50 N is applied to the body. What is the friction force acting on the body?

An object is displaced by r → = ( 5 m ) i ^ − ( 2 m ) j ^ {“version”:”1.1″,”math”:”\vec{r}=(5\,m)\hat{i}-(2\,m)\hat{j}”} while it is acted upon by  F → = − ( 8 N ) i ^ + ( 22 N ) j ^ . {“version”:”1.1″,”math”:”\vec{F}=-(8\, N)\hat{i}+(22\,N)\hat{j}.”}What is the work done on the object by this force?
