Spool Spinning
kwestion rotational kinematics?
Pardon the alliteration: The thread is wound around a spool cylinder, 1.5 cm radius, whose central axis is fixed on a support. The wire is drawn steadily, causing the tail to rotate at a steady pace, but it takes 4 s to start 8 m of thread. What is the angular velocity of the coil, while the thread is removed?
dr = RT = d / t 2 m / s C = 2 * pi * 1.5 C = 3 * pi cm make a porportion, angle/2pi = d / circumference. x / 2 * pi = 2 / 3 * pi * 10 ^-3m x / 2 = 2 / 3 * 10 ^-3m x = 4 / 3 * 10 ^ -3 x = 1333.33 rad / s check: 1333 , 33 rad / s * 4s = 5333.33 rad 5333.33 rad / 2 * pi = rotations. (5333.33 / 2 * pi) * 2 * pi * 0.0015 m = distance. Im really sorry if I explained very badly, I learned in Spanish so its hard to explain in English.
