This diagram shows a baseball’s motion.

a baseball is shown at 5 positions along an arc from left to right. p is far left and r is center, with q halfway between p and r. t is far right with s halfway between r and t.
which statement is best supported by the diagram?

kinetic energy becomes potential energy between points r and s.
maximum potential energy is at point p.
maximum potential energy is at point r.
potential energy becomes kinetic energy between points p and q.
