5. It's time we got back to that spool! (Ifyou have a spool of thread handy, you could try it. The inner radius, where the thread is wrapped, needs to be smaller than the outer radius that rolls. Ayo-yo is perfect, if you have one.) pull the cord F pull the cord (perspective View) (side View) A. The spool starts out sitting still on the table, and you pull the cord to the right. In which direction does the spool accelerate and why? 1 .'. B. Suppose the moment of Inertia of the spool IS I ' IR 3 , where R is the radius of the outer discs, and suppose the inner radius, where the cord is wrapped, is R/Z. Ifyou pull in such a way that the . F . . force by the cord on the spool Is 5, find the acceleration a of the center of mass ofthe spool. Here's some help, ifyou'd like guidance: I. There's a net torque on the wheel, by the pull ofthe cord and by the friction force to the left by the table, that causes an angular acceleration. ||. There's a net force on the wheel, by the cord and friction, that causes a linear acceleration. \"I. That the wheel is rolling means the angular a and the linear acceleration a are related... How . I,c\\ /Z; (@3- 1 and why? ""3 ' C. Say you decide to pull not horizontally, but at an angle. Don't pull too hard. There's an angle for which the spool will not move. Try it! What is that angle c1
