A group should first create a list of creative ideas, possible solutions, etc. Then, once they have all the possibilities in front of them but before making a final decision, they should come up with the “criteria” they will use to judge the worthiness, desirability, effectiveness of each solution on the “possible” list.

Which of the following is the decision-making process whereby the group eliminates all the options that don’t meet their selected criteria and then the person with the most expertise in the subject matter of the project is asked to make the final decision?  

An object of mass 110.0 kg moving “east” with 23.0 m/s collides head-on and sticks to an object of 250.0 kg moving “west” with 20.0 m/s. What is the magnitude of the final speed of the composite? Use three significant digits.

Momentum is always conserved when dealing with two particle collisions just before and just after the collision when there are no external forces acting on the system.

Calculate the magnitude of the momentum of a particle of mass 1.35 kg whose kinetic energy is 24.5 J. Answer to 3 significant figures. 

A rotator starts from rest and accelerates to an angular speed of 115 rpm in 12.0 s. How many revolutions does the rotator make in the first 5.30 s? Three significant digits please.

Surfaces which do not lie at right angles to the source of illumination or are obscured by other surfaces and which reflect little or no light are defined as?
