Physics
Problem
A string clamped at both ends is vibrating. At the moment the string looks flat, the instantaneous transverse velocity of points along the string, excluding its end-points, must be
(a) zero everywhere.
(b) dependent on the location along the string.
(c) not zero anywhere.
(d) non-zero and in the same direction everywhere.
