directed downward.

Answer:

  1. If you drop a feather and a coin at the same time in a tube filled with air, the coin will reach the bottom of the tube first. This is because the feather is affected more by air resistance than the coin, which is denser and less affected by air resistance.

  2. For the ball tossed vertically upward, the acceleration of the ball is always directed downward. This is due to the force of gravity acting on the ball, which pulls it back toward the Earth regardless of its motion (upward or downward).
