A 52.0-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/s^{2} |

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 |

Step 1

Since we are entitled to answer up to 3 sub-parts, we’ll answer the first 3 as you have not mentioned the subparts you need help with. Please resubmit the question and specify the other subparts you’d like to get answered.

Step 2

Given:

Mass of child = 52 kg

Diameter of the wheel = 26 m

Radius of the wheel = 13 m

Angular velocity = 4 rev/min

=0.419 rad/s

Step 3

Part (a): Centripetal acceleration of ...
