Q:
A feather and an iron ball are suspended inside a vacuum chamber. The feather is half a meter farther from the ground than the iron ball. The feather is dropped and just when it is even with the iron ball the iron ball is dropped. Which reaches the ground first, the feather or the iron ball? They will both hit at the same time because they both experience the same acceleration. The feather will hit the ground first. The iron ball will hit the ground first. You can't tell from the information given. An object is thrown straight up and then eventually comes straight down. At its highest point, the velocity and acceleration are both zero. the velocity is zero and acceleration is downward, not zero. the velocity is zero and acceleration is upward, not zero. the velocity is upward and the acceleration is zero. the velocity is downward and the acceleration is zero. the velocity and acceleration are both downward. the velocity and acceleration are both upward.Explanation / Answer
