Hello, I encountered a mass on a string problem in which the mass, moved from the equilibrium, gets a harmonic motion. The catch, however, is that the mass of the string is not neglected. On the lecture, the prof. wanted to calculate, for some reason, the complete kinetic energy of the system:
(1/2)∑mivi2 =(1/2)∫v2dm
where the vi and mi are parts of the string and their velocities. After that, he said that v(x) has the next form:
v(x)=A+Bx
Can anyone elaborate on why the velocity has the dependence written above?
