WebSolution. Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string. WebSo the formula for kinetic energy is that it's equal to 1/2 times the mass of the object, times the magnitude of its velocity squared, or another way to think about it, its speed squared. And so given this formula, pause the video and see if you can calculate the kinetic energy for each of these running backs.
