Q. A uniform disk of mass 0.70 kg and radius 7.0 cm is mounted in the center of a 10 cm axle and spun at 800 rev/min. The axle is after that placed in a horizontal position with one end resting on a pivot. The other end is given an initial horizontal velocity such that the precession is smooth with no mutation.

(i) What is the angular velocity of precession?

(ii) What is the speed of the center of mass all through the recession?

(iii) What are the magnitude and direction of the acceleration of the center of mass?

(iv) What is the vertical component of the force exerted by the pivot?

What is the horizontal component?
