During a shot put event athletes throw a very heavy round ball called a shot as far as possible. The graph shows the vertical velocity of a shot that was thrown by an athlete. Which statement is an accurate analysis of the vertical motion of the shot?
Answer choices:
A. The direction of the Velocity is upward for both the first second and the last second, and the acceleration remains constant for the entire period.
B. The direction of the velocity is downward for both the first second and the last second and the acceleration decreases and during the entire period.
C. The direction of the velocity is upward for the first second and then downward for the last second, and the acceleration decreases during the entire period.
D. The direction of the velocity is upward for the first second and then downward for the last second, and the acceleration remains constant for the entire period. ​

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
