Homework Help: Physics

Posted by Anonymous on Friday, February 26, 2010 at 12:10pm.

A heavy piece of hanging sculpture is suspended by a 90 cm long, 5.0 g steel wire. When the
wind blows hard, the wire hums at its fundamental frequency of 80 Hz. What is the mass of the
sculpture?

---

Velocity=(0.9)(80)=72m/s

T=V^2*u
=(72)^2*(0.005kg/0.9m)
=28.8 N

T=W
28.8=(mass sculpture + mass wire)*g

..im not sure where I am going wrong...or if any of this is correct..
