It is part of the answer. Q4: f=v/λ = 343/1.14= 300.877= 301[Hz] approx Q7: large amplitude Q8: 440-(15/5)= 437[Hz] Q9: f= nv /2L -> v=f2L/n = 557.14*2*0.7/6= 129.999= 130[m/s]

Using conservation of energy : mgh+(1/2)mv^2=(1/2)m( nv )^2 2gh+v^2=(n^2)(v^2) 2gh=(n^2)(v^2)-v^2 2gh=(n^2-1)(v^2) v^2=2gh/(n^2-1) v=sqrt(2gh/(n^2-1))
