Your friend, an artist, has been thinking about an interesting way to display a new wind sculpture. her design invlodes attacjing two 75cm pieces of wire from two hooks on the cieling that are approx. 50cm apart and then hang the 25kg sculpture from a 50cm horizontal bar with insignificant mass. the ratio of fundamental frequencies of the two sounds is 3: 2. your friend tells you that she has been successful in hanging the sculpture but not in a choosing the point along the bar to hang the scupture giving desired sound. desperate for success she knows that you are taking physics 221 and asks for your . before you tackle anakysis, you use your knowledge of waves to gather some more info. you takw a sample of the wire back to lab and measure its linear mass density to be 1.0g/m. you also determine that it is some sort of steel alloy from its color and the fat that it is strongly attached to a bar magnet. where along the bar should the 25kg sculpture be hung to achieve the proper ratio of frequencies? what notes(frequencies) will the two strings play?

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2 . how much is the spring compressed x from its natural length?
