A uniform string of length \( \mathrm{L} \) and total mass \( \mathrm{M} \) is suspended vertically and a transverse pulse is given at the top end of it. At the same moment a body is released from rest and falls freely from the top of the string.
\( P \) How far from the bottom does the body pass the pulse.
