Two forces, oppositely directed, act on a body. The force acting toward the right is twice as strong as the force acting toward the left. Describe the motion of the body. |

Suppose a person is stranded on a frozen lake of perfectly smooth (frictionless) ice. Think of a method for the person to use to reach the shore of the frozen lake. |

The tidal force that the Earth exerts on the Moon is stronger than that exerted by the Moon on the Earth. Explain why this is so. |

The tidal acceleration due to the Moon is twice as large as the tidal acceleration due to the Sun. Show how this leads to a total tidal acceleration about three times as large for spring tides as for neap tides. |
