A 44.0-kg child takes a ride on a Ferris wheel that
rotates four times each minute and has a diameter
of 26.0 m.
(a) What is the centripetal acceleration of the child?
magnitude
m/s2
direction
---Select--- toward the center of the path away
from the center of the path tangent to the path The
magnitude is zero.
(b) What force (magnitude and direction) does the seat exert on the
child at the lowest point of the ride?
magnitude
N
direction
---Select--- up toward the center down away
from the center tangent to the left tangent to the
right The magnitude is zero.
(c) What force does the seat exert on the child at the highest
point of the ride?
magnitude
N
direction
---Select--- up away from the center down
toward the center tangent to the left tangent to the
right The magnitude is zero.
(d) What force does the seat exert on the child when the child is
halfway between the top and bottom? (Assume the Ferris wheel is
rotating clockwise and the child is moving upward.)
magnitude
N
direction
° counter-clockwise from the horizontal
