C) If the ball was thrown in any direction other than straight up, there
would be two accelerations, one in the down direction and the other in
the lateral direction the ball was thrown.
•
Yes, the answer to b does depend on the angle with respect to the
ground at which the ball is thrown. This is due to the fact that the
velocities of the ball across the path vary. Thus, one must consider the
components to determine the actual acceleration just before it hits the
ground.
•
C) Both a and b depend on the angle with respect to the ground the ball
was thrown because it will change the direction and the magnitude of
the acceleration.
