A rope hangs from a tree that is on Earth's surface. Student X holds on to the end of a rope and hangs from rest. Student Y exerts a force onto student X so that student X undergoes simple harmonic motion while hanging onto the rope. Air resistance is considered to be negligible. Graph 1 shows the vertical position of student X as a function of time. Graph 2 shows the speed of student X as a function of the student's vertical position.

A rope hangs from a tree that is on Earth's surface. Student X holds on to the end of a rope and hangs from
rest. Student Y exerts a force onto student X so that student X undergoes simple harmonic motion while
hanging onto the rope. Air resistance is considered to be negligible. Graph 1 shows the vertical position of
student X as a function of time. Graph 2 shows the speed of student X as a function of the student's vertical
position.
