Suppose you are standing on the center of a merry-go-round that is at rest. you are holding a spinning bicycle wheel over your head so that its rotation axis is pointing upward. the wheel is rotating counterclockwise when observed from above.
for this problem, neglect any air resistance or friction between the merry-go-round and its foundation.
suppose you now grab the edge of the wheel with your hand, stopping it from spinning. what happens to the merry-go- round?
a) it remains at rest.
b) it begins to rotate counterclockwise (as observed from above).
c) it begins to rotate clockwise (as observed from above).
d) cannot be determined from the information given.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
