Please help- Make a triangle with masking tape on the floor. The first side should be 5 meters directly north (label it A), the second should be 5 meters directly east (label it B) and the third side should connect the two (Label this side C).
Using a stopwatch, time how fast you can walk the length of the side A, side B and side C. You only need to do this once.
Record these times.
Calculate your speed and your velocity.

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
