Angling for a New Idea Conservation of L A) I Spin while holding two dumbbells close to your body with your arms folded, spin around on the ro- tating chair (be sure your feet are not touching the chair or ground). Next quickly push the dumbbells straight out to arm's length When you moved the dumbbells away from your trunk, was there a net torque applied to the system (you + rotating chair + dumbbells)? Explain whether or not and...

A large plate is balanced at its center and two students of equal mass stand at its center. The plate is rotated on a frictionless pivot about an axis through its center and perpendicular to its face. The students then begin to walk out towards opposite edges. (Select T-True, F-False, I-Increases, D-Decreases, S-Stays the same. ). A) The students produce no net torque on the plate. B) The rate of rotation ... as the students walk outward. C) The students...

Suppose the surface in the example is sloped as shown in the
figure, but everything else remains the same. Determine the
equation for the acceleration in this case using angular momentum
and torque. Let a positive acceleration represent acceleration of
m2 up the surface. (Use the following as
necessary: m1, m2,
M, θ, and g.)
A sphere of mass m1 and a block of mass m2 are connected by a light cord that passes over a pulley as shown in...

Up A #4. [Gyroscope Wheel] A rubber wheel on a steel rim spins freely on a horizontal axle that is suspended by a fixed pivot at point P. When the wheel spins at a rate of 4.00 rev / s, it precesses smoothly about point Pin a horizontal plane with a period of 3.50 s. The wheel's outer radius is 15.0 cm, and it's total mass is measured to be 1.12 kg, 60% of this being the spinning wheel and...

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...
