Find an angular speed of a skater.
A 60.0 kg skater begins a spin with the angular speed of 6.00 rad/s. By changing the position of her arms, the skater decreases her moment of inertia by 50%. What is the skater's final angular speed?

A pure and very thin SI slice is placed inside of and in parallel with a parallel-plate capacitor which has a spatially constant electric field. The electron potential energy inside the Si varies linearly with distance i ...
A pin is thrown tumbling in the air. What is the probability distribution of the angle θ 1 between the pin and the vertical at a moment while it is in the air? The tumbling pin is photographed. What is the probability di ...
How many bits are needed to specify a selection of K objects from N objects? (N and K are assumed to be known and the selection of K objects is unordered.) How might such a selection be made at random without being waste ...
On May 9, 2007, CBS Evening News had a 4.3 point rating. (Ratings measure the number of viewers.) News executives estimated that a 0.1 drop in the ratings for the CBS Evening News corresponds to a $5.5 million drop in re ...
1. What are the Stanton and Peclet numbers and how are they related to other convective mass-transfer dimensionless numbers? 2. In applying dimensional analysis to explain mass-transfer coefficient, one must consider the ...
Two hockey pucks of equal mass approach each otherhead-onwith equal speeds of 8.7 m/s. They collide and one puck leaves the collision with a speed of 6.2 m/s. What is the speed of the other puck after the collision?
Two ordinary dice are thrown repeatedly; the outcome of each throw is the sum of the two numbers. Joe Shark, who says that 6 and 8 are his lucky numbers, bets even money that a 6 will be thrown before the first 7 is thro ...
