4 Points A baseball is hit into the air at an initial speed of 36.6 m/s at an angle of 50 degrees above the horizontal.  At the same instant, the center fielder starts running away from the batter and catches the ball 0.914 m above the level at which the ball was hit.  If the center fielder is initially 110 meters from home plate, what must be his average speed?

5 Points A football is kicked downfield at an angle of 33 degrees and lands 60 yards (54.864 meters) away.  How fast was the initial velocity of the football?

4 Points The Graph Below Represents the Motion of an object Each Segment (A, B, C, D, E, F) Represents a section of the graph Answer the following with a single Letter that most accurately matches the motion described in the question.  Then Explain the Reasoning behind your choice Letters may be used more than once and not all letters will be used to each graph   Refer to the diagram above.  (Use the Letter for the graph segment to denote the answer) __________ Which section represents a constant velocity other than zero? __________ Which section represents the greatest acceleration? __________ Which section represents a changing acceleration? __________ Which section represents the greatest displacement?

NF-kB is a transcription factor that plays an important role in the inflammatory response. Under normal conditions, NF-kB is inactive because it is sequestered in the cytoplasm by interaction with the inhibitory protein I-kB. Activation of NF-kB requires the phosphorylation and subsequent degradation of I-kB.  The I-kB kinase, IKK, is the enzyme responsible for this phosphorylation.  IKK has two substrates, I-kB and ATP, and produces two products, I-kB -P and ADP.  It has been found that IKK follows the reaction mechanism shown below.  This mechanism is known as _______.

4 Points The Graph Below Represents the Motion of an object Each Segment (A, B, C, D, E, F) Represents a section of the graph Answer the following with a single Letter that most accurately matches the motion described in the question.  Then Explain the Reasoning behind your choice Letters may be used more than once and not all letters will be used to each graph   Refer to the diagram above.  (Use the Letter for the graph segment to denote the answer) __________ Which section shows accelerated motion? __________ Which section shows the object at rest? __________ The object is always moving toward the starting point in which section ? __________ Which section represents a constant negative velocity?
