1. A ball is thrown vertically upward from the surface of the earth. Which of these is (are) zero when the ball has reached the maximum height: the speed of the ball; the velocity of the ball; the acceleration of the ball?
2. An eagle is flying due east at 8.9 m/s carrying a gopher in its talons. The gopher manages to break free at a height of 12 m. What is the magnitude of the gopher's velocity as it reaches the ground? Note: effects of air resistance are not included in this calculation.
