A car moves in a straight line towards the east with a certain speed v, in a first period of time the acceleration vector of the car points to the east, then in a second period of time the direction of the acceleration vector changes and now it points towards the West. Considering that the car always kept moving towards the east and with the information provided we can ensure that: a) It is not possible to determine whether the magnitude of the velocity vector increased or decreased since we do not have the numerical values to carry out the procedure. b) During the first period of time the magnitude of the velocity vector increased and during the second period of time the magnitude of the velocity vector also increased. c) During the first period of time the magnitude of the velocity vector increased and during the "second period of time the magnitude of the velocity vector decreased. d) During the first period of time the magnitude of the velocity vector decreased and during the second period of time the magnitude of the velocity vector increased.

Question 21 Assume the position of a person traveling along a straight hiking trail is given by the graph depicted. The input to the function is time in hours, and the output is position in miles from the only outhouse on the trail.
