A block hangs in equilibrium from a vertical spring. When a second identical block is added, the original block sags by 5.00 cm. What is the oscillation frequency of the two block system?
F=kx = mg
but for the second block we have
setting the x equal..
f= 1/2pi sqrt (k/m)
put that k int the expression, and you have the answer.
