Question
A traveling wave on a taut string with a
tension force T is given by the wave
function y(x,t) = 0.1 sin(4ttx+100t) where x
and y are in meters and t is in seconds. The
linear mass density of the string is u = 0.2
kg/m. If the tension is multiplied by a factor
of four, while keeping the same amplitude,
same wavelength, and same linear mass
density, then the new kinetic energy
associated with one wavelength on the
string is
20 J
40 J
10 J
5 J
