Answer: a. On Mars, the free fall acceleration is about one third of that on Earth. This means that the gravitational pull on Mars is weaker compared to Earth.
When you throw a ball upward on Mars with the same velocity as you would on Earth, the ball will experience a weaker gravitational force pulling it back down. As a result, the ball will reach a lower maximum height compared to Earth.
b. The flight time of the ball would also be affected by the weaker gravitational pull on Mars. Since the ball is thrown with the same initial velocity, it will still follow a similar trajectory as on Earth. However, due to the weaker gravitational pull, the ball will take longer to reach its maximum height and also longer to return back to the ground. Therefore, the flight time of the ball on Mars will be longer compared to Earth.
In summary, when throwing a ball upward with the same velocity on Mars as on Earth, the ball will reach a lower maximum height on Mars and have a longer flight time compared to Earth due to the weaker gravitational pull.
