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 maintenance role that a group member would play whereby they intervene when they see that group conflict is threatening the cohesiveness of the group?  

Which of the following is the procedural role that a group member would play whereby they arrange times and places for meetings, send out reminder memos and make sure the group’s physical needs are met (supplies, refreshments, etc.)?  

Which of the following is the procedural role that a group member would play whereby they manage the flow of conversation so that all members have equal opportunities to participate?  

A secret chamber is opened by applying a force of 300 N perpendicular to the plane of the door, 0.80 m from the hinges. Calculate the torque due to this force about an axis through the hinges. Round to two significant digits please. 

A merry-go-round turns at a constant rate of 6 complete rotations per minute. What is its angular speed in radians per second?

Assume a rotator’s angular position is given by , where and are constants. If at , t = 0 , rads/s and  rads/s2, what is the constant ? Three significant digits.

A secret chamber is opened by applying a force of 300 N perpendicular to the plane of the door, 0.80 m from the hinges. Calculate the torque due to this force about an axis through the hinges. Round to two significant digits please. 

An impulse enacted on a 2.0 kg particle results in the change in velocity according to the velocity versus time graph. Calculate . Use two significant digits.
