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?
The length of a string is 456 cm. It is held ?xed at each end. The string vibrates in three sections; i.e., the string has three antinodes and string vibrates at 180 Hz.

A cement block accidentally falls from rest from the ledge of a 74.8-m-high building. When the block is 18.4 m above the ground, a man, 2.10 m tall, looks up and notices that the block is directly above him. How much time, at most, does the man have ..
Throughout a hard sneeze, your eyes may shut for 0.41 s. If you are driving a car at 98 km/h during such a sneeze, how far does the car move during that time.
A 1200 N uniform boom is supported by a cable perpendicular to the boom, as in Figure P8.28. The boom is hinged at the bottom, and a 2000 N weight hangs from its top. Find out the tension in the supporting cable and the components of the reaction ..
A stone with a mass of 0.900 kg is attached to one end of a string 0.900 m long. The string would break if its tension exceeds 60-N. The stone is whirled in a horizontal circle on a frictionless tabletop.
