An ice skater has a moment of inertia of 5.0 kg. M^2 when her arms are outstretched , and at the time she is spinning at 3.0 rev/s . If she pulls in her arms and decreases her moment of inertia to 2.0 kg. M^2 , how fast will she be spinning
Answers: 3
(Eq. 1)
- Moment of inertia of the ice skater when her arms are outstretched, measured in kilogram-square meters.
- Angular speed when arms are outstretched, measured in revolutions per second.
- Moment of inertial of the ice skater when her arms are pulled, measured in kilogram-square meters. 
- Angular speed when arms are pulled, measured in revolutions per second. 
, 
and 
, the angular speed when arms are pulled is:

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
