A disk with mass m = 5.4 kg and radius R = 0.47 m hangs from a rope attached to the ceiling. The disk spins on its axis at a distance r = 1.34 m from the rope and at a frequency f = 19.5 rev/s (with a direction shown by the arrow).
1) What is the magnitude of the angular momentum of the spinning disk?
2) What is the torque due to gravity on the disk?
3) What is the period of precession for this gyroscope?
4) What is the direction of the angular momentum of the spinning disk at the instant shown in the picture?
5) What is the direction of the precession of the gyroscope?
A 0.25 kg puck is initially stationary on an ice surface with negligible friction. At time t = 0, a horizontal force begins to move the puck. The force is given by F= (12.0 - 3.00t^2)i, with F in newtons and t in seconds, and it acts until its mag..
