During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 148-g baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 10.1 m/s, shatters the glass as it passes through, and leaves the window a...

A charge Q = +4.5 uC is located at the origin and is fixed so that it cannot move. A small object with mass m = 2.0 g and charge q = +8.0 uC is released from rest at point A on the x-axis at x = 2.0 cm. The small object moves without friction along the x-axis under the influen...

"You will measure the tension T, the mass m, and the length L of your spring. In terms of these variables, what is the expected frequency of the fundamental standing wave?" I found the fundamental frequency to be: f = 1/2L * sqrt(T/m/L)?

"A slinky that satisfies v = sqrt(T/_mu) is stretched 12m. The mass of the slinky is 0.8kg. The tension on the slinky is 4N. What is the expected wave speed?" To get mu, I divided the mass by the length then plugged that into the equal and solved for v but I'm no...
