NT3E-WWT36: VELOCITY VS. TIME The graphs show the velocity versus time for two boats traveling along a narrow channel that runs east to west. The scales on both axes are the same for the two graphs, and east is positive. In each graph, a point is marked with a dot. A student who is asked how the acceleration at the marked point for the object in graph A compares to the acceleration at the marked point for the object in graph B states: GRAPHS-ACCELERATION A Velocity Time B Velocity -Time "I think that at the marked point the boat in graph B has the larger acceleration because the boat in graph A is at rest and its acceleration is zero." What, if anything, is wrong with this student's contention? If something is wrong, identify it, and explain how to correct it. If it is correct, explain why.

Bacteria move back and forth using their flagella (structures that look like little tails). Speeds of up to 50m/s(50106m/s) have been observed. The total distance traveled by a bacterium is large for its size, whereas its displacement is small. Why is this?
Unreasonable results A dolphin in an aquatic show jumps straight up out of the water at a velocity of 15.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known, and identify its value. Then, identify the unknown and discuss how you chose the appropriate equation to solve for ft. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long a time is the dolphin in the air? Neglect any effects resulting from his size or orientation.
Between t=0 and t=t0 , a rocket moves straight upward with an acceleration given by a(t)=ABt1/2 , where A and B are constants. (a) If x is in meters and t is in seconds, what are the units of A and B ? (b) If the rocket starts from rest, how does the velocity vary between t=0 and t=t0 ? (c) If its initial position is zero, what is the rocket’s position as a function of time during this same time Interval?
