A uniform disk turns at 2.7 rev/s around a frictionless central axis. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk(Figure 1) . They then turn around the spindle with their centers superposed. What is the angular frequency in rev/s of the combination?
A uniform disk turns at 3.7 rev/s around a frictionless spindle. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk. They then turn together around the spindle with their centers superposed. What is the angular frequency in rev/s of the combination?
Problem 8.72 A uniform disk turns at 2.6 rev/s around a frictionless central axis. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk . They then turn around the spindle with their centers superposed. Part A What is the angular frequency in rev/s of the combination? Express your answer using two significant figures.
A uniform disk turns at 3.6 rev/s around a frictionless spindle. A non rotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk . They then both turn around the spindle with their centers superposed. What is the angular frequency in rev/s of the combination? please express answer in proper significant figures and rounding.
What is the angular frequency in rev/s of the combination? A uniform disk turns at 2.4 rev/s around a frictionless spindle. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk(Figure 1). They then both turn around the spindle with their centers superposed. Figure 1 of 1
3. A uniform solid disk of turns around a frictionless spindle with an angular speed wo A hoop with the same mass and radius is dropped onto the disk such that it sticks and begins rotating with the disk. What is the final angular speed? What fraction of the kinetic energy is lost?
A potter's wheel is rotating around a vertical axis through its center at a frequency of 2.0 rev/s . The wheel can be considered a uniform disk of mass 4.7 kg and diameter 0.30 m . The potter then throws a 2.8-kg chunk of clay, approximately shaped as a flat disk of radius 7.0 cm , onto the center of the rotating wheel.A) What is the frequency of the wheel after the clay sticks to it? Ignore friction.
6_1. A majorette in a parade is performing some acrobatic twirlings of her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm. a. Initially, the baton is spinning about a line through its center at angular velocity 3.00 rad/s. (Part A figure) What is its angular momentum? Express your answer in kilogram meters squared per second. 6_2. Learning Goal: To understand how to use conservation of angular momentum to solve problems involving...
