The tip of a fishing rod droops by 20 cm when a 50 g sinker is attached to the line and hangs motionless. If the sinker bobs up and down, what is its frequency of oscillation?
I know the answer is f = 1.11 Hz but I do not know how to do the problem. This is a trigonometry based physics course so please do not use calculus in your answer. Thank you

3. (3 points) Suppose you are fishing, and you cast out 30 feet of line (measured from the tip of the rod to the sinker). When the sinker hits the bottom of the river, it makes a 130° angle with your fishing pole (line taught and rod level). If the tip of your rod is 5 feet above the...

Review A 76 g , 40-cm-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 11 g ball of clay traveling horizontally at 2.2 m/s hits and sticks to the very bottom tip of the rod. A) To what maximum angle, measured from vertical, does the rod (with the attached ball of clay) rotate? Express your answer to two significant figures and include the appropriate units.

" A mass hanging from a vertical spring is somewhat more complicated than a mass attached to a horizontal spring because the gravitational force acts along the direction of motion. Therefore, the restoring force of the oscillations is not provided by the spring force alone, but by the net force resulting from both the spring force and the gravitational force. Ultimately, however, the physical quantities of motion...
