Answer:
The ball on the moon would have a more straight path than on the Earth, and it would have a longer range
Explanation:
In both cases, the motion of the ball is the motion of a projectile, which has a parabolic trajectory. In fact, the path is the resultant of two indipendent motions:
- A horizontal uniform motion, with constant horizontal velocity 5 m/s
- An accelerated vertical motion, with constant acceleration downward equal to the gravitational acceleration of the planet
On the Moon, the value of the gravitational acceleration is about 1/6 that of the Earth. This means that the downward acceleration of the ball on the Moon is smaller than on the Earth: so, the ball will take more time to reach the ground on the Moon, and so it will have a longer range, and a more straight trajectory.
