APSC112 Problems 1A: Kinematics Problems 1 is in 3 parts and covers all the material in Section 1 of the course. Dynamics problems cannot be done until a clear understanding of kinematics has been obtained. These problems, and possibly others, will be discussed in the first tutorial. Have the formula sheets handy as you work through the problems, both at home and in tutorials. Make sure that you examine the posted solutions of any that you are unable to finish. A1. Fig. A1 shows 2 identical pulleys, A and C , on fixed axles joined by a belt B which does not slip. Each pulley can be considered to be 2 disks of radii r and R welded together. Cords supporting masses m and M are wound around two of the disks as shown. (i) If A is rotating with angular velocity ω A and acceleration α A , find the angular velocity and acceleration of pulley C , and the linear velocities and accelerations of the 2 masses. (ii) Pulley A accelerates with constant angular acceleration α A = 0 . 10 rad/s 2 and, at time t = 0, ω 0 A = 15 . 5 RPM. Find the time

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
