Ok. So the speed of sound is 343 m/s. The wavelength formula equals velocity/ frequency. So wavelength should equal 343/425 which equals about 0.8071 m. Since I still have wavelength/2, that means I divide 0.8071/2 equalling 0.4035. So for my equation to solve for x= x|S1 - S2| = wavelength...

Two loudspeakers are placed 3.00 m apart horizontally.They emit 425 Hz sounds, in phase. A microphone is placed d= 3.20 mid distant from a point midway between the two speakers, where an intensity maximum is recorded.
(a) How far must the microphone be moved to the right to...
Update: I got the answer wrong. My answer was < 0.4242,0, -.9056>. The solution was <0.914,0, -0.407>. Not quite sure how to get to that answer but anyone feel free to explain if you understand.
Homework Statement
A 0.5 kg block of ice is sliding by you on a very slippery floor at 2.5 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.0035 seconds. The block eventually slides at an angle of 24 degrees from its original...
Sorry, I am seem to be a bit confuse with the statement of using the force equations to find the new position than using velocity. Do I have to manipulate the force equations and set them equal to delta r?
Homework Statement
A spring has a relaxed length of 35 cm (0.35 m) and its spring stiffness is 10 N/m. You glue a 70 gram block (0.070 kg) to the top of the spring, and push the block down, compressing the spring so its total length is 12 cm. You make sure the block is at rest, then at time t =...
