Question

I already solved the problem. I just don't understand why it is necessary to divide 3.13 m by 2. Could someone please explain? Also, why is it sin 20 and not cos 20?

ter edge (r - 0.0568 m). the angular speed is 3.50 revis. * the constant tangential speed at which music is detected dhe angular speed (in rev/s) for music at a distance of 0.0249 m * the outer ed sed (a) the COMO rag d (b) the angu Additional Problem its angular speed is 0.571 radis. At this time, the total = (centripetal plus tangential) makes an angle of 35.0" with red radius. (The situation is similar to that in Figure 8.12b.) Whal. on the center of a CD. 4. One end of a rop he end of a rope is tied to the handle of a horizontally-oriented and niform door. A force F is applied to the other end of the rope as Chown in the drawing. The door has a weight of 158 N and is hinged on the right. What is the maximum magnitude of F for which the door will remain at rest?
