A fisherman poles a boat as he searches for his next catch. He pushes parallel to the length of the light pole, exerting a force of 245 on the bottom of a shallow lake. The pole lies in the vertical plane containing the boat's keel. At one moment, the pole makes an angle of 34...

A woman is sitting in a boat at anchor on a lake. Her boat bobs up and down once every 2.0s. She notices that when the front of her 3.0m long boat is at one wave crest, a second crest is at the middle of her boat, and a third is at the end. What is the frequency of the waves...
