A pulse is moving toward the end of a spring with a speed of 80 cm/s. It is not known whetherthe end is a fixed end or a free end.The diagrams below show the shape of the pulse at t = 0 s and at t = 1 s.Is the end of the spring a free end or a fixed end? Explain. If there is not enough information,state so explicitly.Write your explanation on paper and support your explanation with a clear diagram.
