- Question 9. Michael Jordan, formerly of the Chicago Bulls basketball team, has some fanatic fans. They claim that he is able to jump and remain in the air for two full seconds from launch to landing. Evaluate this claim by calculating the maximum height that such a jump would attain. For comparison, Jordan's maximum jump height has been estimated at about one meter. Ans: 4.9 marrow_forwardA girl starts from the point A walks 8.0 m east, then 5.0 m south 3.0 m west, and finally 4.0 m to the north to a point B.
