Suppose you have a machine with a metal disk in it mounted to spin about its center. If the disk has a radius of 0.7 meters, and a mass of 5 kilograms, how much force would you have to apply to its edge to get it spinning at 1200 revolutions per minute. Assume the force is applied for 8.3 seconds. Give your answer in newtons (N).
The figure below represents a bicycle wheel comprised of a rim with a radius of R = 0.5 m and mass of M = 200 g, to which someone has added two m = 30 g sensors that are separated by an angle of = 110°. The axis of rotation for the wheel is at its center, as represented by the vector symbol, for a direction into the page. m = 30 g R = 0.5 m M = 200 g m = 30 g a) Where is the center of mass of the wheel/sensor system? b) What is the rotational moment of inertia of the wheel/sensor system around its axis of rotation?
18) Consider an adult and a child riding their bikes. The adult's bicycle has tires with an outer diameter of 700 centimeters. The child's bicycle has tires with an outer diameter of 350 centimeters. The adult bicycle's tires are rotating with an angular velocity of 4.0 radians per second. If the child cyclist is traveling along the road at the same speed as the adult, then what angular velocity must the child's bicycle's tires be rotating at? [Assume the tires are rotating without slipping as the cyclists ride]. A) 1.0 radians second per B) 2.0 radians per second C) 4.0 radians per second D) 8.0 radians per second E) 16.0 radians per second abnoose e G

A kid runs towards the edge of a merry-go-round that is not rotating and jumps on. The merry-go-round then rotates with a constant angular velocity ω. Assume that the kid has a mass of 40 kg and is initially running at a speed of 2 m/s tangent to the edge of the merry-go-round. The merry-go-round is a uniform disk with a mass of 120 kg and a radius of 2 m. Assume that it rotates without friction. What is the final angular velocity ωf (in radians/s) of the merry-go-round (with the kid riding)? Please write out steps, not type-I have dyslexia

NASA physicians need to know whether the contents of astronauts' skulls (brain, eyes, eardrums, etc.) move so much during rotational maneuvers that injury might be caused. If you are an astronaut in a spinning spacecraft and have an initial angular displacement of 3.14 radians, an initial angular velocity of 3.683 radians per second, and an angular acceleration of 0.02 radians per second squared, what distance will your eyes have traveled around the center of your skull after 26.83 seconds?
Two window washers, Bob and Joe, are on a 3.00-m-long, 370-N scaffold supported by two cables attached to its ends. Bob weighs 780 N and stands 1.00 m from the left end, as shown in the figure below. Two meters from the left end is the 500-N washing equipment. Joe is 0.500 m from the right end and weighs 880 N.
