Homework Statement
John is listening to a horn. He knows the frequency of the horn is 300 Hz when both he and the horn are at rest. If he hears a pitch of 270 Hz, there are clearly several possibilities. For each of the following statements, indicate whether it is correct or incorrect...
1. a)Two children, each with mass m = 21.5 kg, sit on opposite ends of a narrow board with length L = 5.6 m, width W = 0.15 m, and mass M = 5.9 kg. The board is pivoted at its center and is free to rotate in a horizontal circle without friction. What is the rotational inertia of the board plus...
