Irma and Harvey start at one end of a street (the origin), run to the other end, then head back. On the way back Irma is ahead of Harvey. Which statement is correct about the distances run and the displacements from the origin?

• Irma has run a greater distance and her displacement is greater than Harvey’s.

• Harvey has run a greater distance and his displacement is greater than Irma’s.

• Irma has run a greater distance, but her displacement is less than Harvey’s.

• Harvey has run a shorter distance, and his displacement is less than Irma’s.

• t = 1 s
  

• t = 2 s
  

• t = 3 s
  

• The speed is of the moose never increases.

Jeanne moves counterclockwise at constant speed around the path shown above. The path is such that the lengths of its segments, PQ, QR, RS, and SP, are equal. Arcs QR and SP are semicircles. Which of the following best represents the magnitude of Jeanne’s acceleration as a function of time t during one trip around the path, beginning at point P?
