it turned out to be much simpler than I thought. no derivatives involved - just assume the cosine component = 1 and then plug and chug to solve for 10sin(pi*x) values. but thank you!

Solved.

Homework Statement Two transverse sinusoidal waves combining in a medium are described by the wave functions y1 = 5.00 sin π(x + 0.900t) y2 = 5.00 sin π(x − 0.900t) where x, y1, and y2 are in centimeters and t is in seconds. Determine the maximum transverse position of an element of...

Homework Statement A block–spring system vibrating on a frictionless, horizontal surface with an amplitude of 4.5 cm has an energy of 24 J. If the block is replaced by one whose mass is twice the mass of the original block and the amplitude of the motion is again 4.5 cm, what is the energy...

I have solved it - thanks anyway!

Homework Statement The average coefficient of volume expansion for carbon tetrachloride is 5.81*10-4 (°C)-1. If a 49.0 gal steel container is filled completely with carbon tetrachloride when the temperature is 10.0°C, how much will spill over when the temperature rises to 27.0°C...
