A 2.00-kg object is free to slide on a horizontal surface. The
object is attached to a spring of spring constant 300 N/m , and the
other end of the spring is attached to a wall. The object is pulled
in the direction away from the wall until the spring is stretched
50.0 mm from its relaxed position. The object is not released from
rest, but is instead given an initial velocity of 2.50 m/s away
from the wall. Ignore...

The figure shows the transverse velocity u versus time
t of the point on a string at x = 0, as a wave
passes through it. The scale on the vertical axis is set by
us = 4 m/s. The wave has form
y(x, t) =
ymsin(kx - ωt + φ).
