Introduction: Centripetal force

More Details: A 36.0-kg child takes a ride on a Ferris wheel that rotates four times each minute and has a diameter of <span class=

"c1">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
