You release a solid disk, a hollow ring, a solid sphere, and a hollow sphere down an incline. Which will arrive at the bottom first? Which will arrive at the bottom last?

Q5A,CE, April 14, 2023 3. Bonnie sits on the outer rim of a merry-go-round, and Klyde sits midway between the center and the rim. The merry-go-round makes one complete revolution every two seconds. Klydes angular velocity is: WEDB Too St (a) (5) (c) (d) (e) same as Bonnies twice Bonnies half of Bonnies 1/4 of Bonnies four times Bonnies VINDER OF B O Year of history bol LATEX F=50N T = F·l Both Change in 2 secu any loveto is nutter 4. Consider a simple rotation situation: a rope is wrapped around the rim of a solid wheel of radius 1.0m and mass M=5kg. Suppose that you pull the rope with a force of 50 N that rotates the wheel 2 radians. What is the work done by you?

Concerning the life of an individual comet, say, from the Kuiper Belt or Oort Cloud.  These objects spend most of their "life" in the outskirts of our Solar System, and then they will "swoop" in toward the Sun when completing a full single orbit.  Can you use the Law of Conservation of Angular Momentum to explain the speed that the comet has when it's farthest from the Sun to when it is closest?  (so you have 2 variables: speed and distance)

A 135-kg merry-go-round in the shape of a uniform, solid, horizontal disk, is set in motion by wrapping a rope about the rim of the disk and pulling the rope with a constant force of 157 N. If the merry-go-round rotates from the rest to an angular speed of 0.4 rev/s in 1.8 seconds, calculate the radius of the disk of the merry-go-round.

Conservation of Angular Momentum. A uniform spherical asteroid rotates around an axis through its CM. Over time, it accretes space dust (of the same density), whose initial velocity with respect to the asteroid’s CM is zero. The asteroid grows from mass m0 to m. How does the period of its rotation change with m? If the asteroid doubles in mass, how and by what factor does its period of rotation change?

Please answer the following question(s): 1. Microwave ovens rotate at a rate of about 1 rev/min. (a) What is this in revolutions per second? Answer: rev/s (b) What is the angular velocity in radians per second? Answer: rad/s 48°F Mostly cloudy

The radius of a flywheel is 0.24 m. If the angular speed of the wheel is 3,408 rpm. Calculate the tangential speed of a point at its tip in meters per second .

A star rotates in a circular orbit about the center of its galaxy. The radius of the orbit is 1.3 x 1020 m, and the angular speed of the star is 5.6 x 10-15 rad/s. How long (in years) does it take for the star to make one revolution around the center?

A compact disc (of radius 0.06m) has an angular speed of 65 radians/second. The linear speed of a point on the perimeter of the compact disc (i.e. located 0.06m from the center) is: A.) 78.2 m/s B.) 3.9 m/s C.) -2.5 m/s D.) 4.5 m/s

The 18-cm-diameter disk in (Figure 1) can rotate on an axle through its center. For general problem-solving tips and strategies for this topic, you may want to view a Video Tutor Solution of Nutcracker. Figure 30 N 457 5 cm 5 cm 20 N -30 N X 20 N 1 of 1 >
