A wave travels along a tight rope in the positive direction of
the x-axis. Its wavelength is 40 cm and its velocity of propagation
along the rope is 80 m/s. The amplitude of the wave is 0.60 cm. In
t = 0 the point of the string at x = 0 is at the point of maximum
oscillation amplitude, y = +A.

A car travels a certain distance along a straight road (in the
+x direction). The distance the car travels as a function of time
is shown in the figure below. When the car changes speed it does so
uniformly. Select the appropriate choice for each statement.
It wont let me post the photo of the graph for some reason, so
here is a link to it
