Extra Problem 2:
The Dingwaives family does not have much use for their old corded phone so they give it to their son Stan in order to conduct physics experiments. The phone cord is 2.06 m long and has a mass of 0.177 kg. Stan notices that a transverse wave pulse travels from the receiver to the phone box in 0.112 s. What is the tension (in Newtons) in the cord?

Habits of an Effective Problem Solver
-
Read the problem carefully and develop a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
-
Identify the known and unknown quantities and record in an organized manner, often times they can be recorded on the diagram itself. Equate given values to the symbols used to represent the corresponding quantity (e.g., v = 12.8 m/s, λ = 4.52 m, f = ???).
-
Use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
-
Identify the appropriate formula(s) to use.
-
Perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
