A sinusoidal wave in a rope is described by

the wave function

y = A sin(k x + ! t) ,

where A = 0.47 m, k = 1 m−1, ! = 26 Hz, x

and y are in meters, and t is in seconds.

vibrator

26 Hz

ì = 3.8 g/m

m

18.8496 m

If the tension in the rope is provided by

an arrangement like the one illustrated above,

what is the value of the suspended mass? The acceleration of gravity is 9.8 m/s2 . The rope

has a linear mass density of 3.8 g/m.
