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 x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
