Rotation Homework 1 .1.) Clearly explain the difference between rotation and a revolution. 2.) What is linear speed called when something is rotating? 3.) At a constant radius, how does the tangential speed change as the angular velocity increases? 4.) At a constant angular velocity, how does tangential speed change as the radius increases? 5.) A ladybug sits halfway between the axis and the edge of a rotating disk. What will happen to the ladybug's tangential velocity if a.) The RPM rate is doubled? b.) The ladybug...

Two ladybugs sit on a rotating disk, as shown in the figure (the ladybugs are at rest with respect to the surface of the disk and do not slip). (Figure 1) Ladybug 1 is halfway between ladybug 2 and the axis of rotation. What is the angular speed of ladybug 1? one-half the angular speed of ladybug the same as the angular speed of ladybug 2 twice the angular speed of ladybug 2 one-quarter the angular speed of ladybug 2...

a) A man jumps off the roof of an office building onto a trampoline 30 m below. His speed is 5 m/s when he umps from the roof and his mass (with all of her gear) is 60 kg. How high will he go when he bounces back up from the trampoline? You can assume his speed at the top of his bounce is zero. b) Describe the changes in mechanical energy that take place during his jump. c) A...

A clarinet player hears the warbling of beats twice per second. When trying to play in tune with the nest of the orchestra she finds that by lowering her frequency, she is in true with everyone else at 440 . What was the clarinet player's initial frequency? 2 children and riding on a marry-go-round. The 1st child sits at the edge of the merry-go-round, the 2nd child sits halfway between the edge and the center. Which of the following is...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...

6. A playground merry-go-round, i.e., a horizontal disc of radius 3 m that can rotate about a vertical axis through its center, is rotating at an angular speed 1/s (measured, as usual, in terms of radians). The moment of inertia of the merry-go-round with respect to that axis is 3000 kg m? A student of mass 80 kg is standing at the center of the merry-go-round. The student now walks outward...
