(a) Two identical sinusoidal pulses move in opposite directions on a stretched string. Kinetic energy of each pulse is k. At the instant they overlap completely, what is kinetic energy of the resulting pulse? (b) �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 same everywhere except at nodes.� Is this statement correct?
