Suppose you are standing on the center of a merry-go-roundthat is at rest. you are holding a spinning bicycle wheel over yourhead so that its rotation axis is pointing upward. the wheel isrotating counterclockwise when observed from above. for this problem, neglect any air resistance or frictionbetween the merry-go-round and its foundation. q.suppose you now grab the edge of thewheel with your hand, stopping it from spinning. what happens to themerry-go-round? it remainsat rest. it begins torotate counterclockwise (as observed from above).it begins torotate clockwise (as observed from above).

the answer is a. at the equator

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
