1.How do horizontal velocities affect vertical velocities?
2. Which ball will hit the ground first if they are dropped at the same time the ball filled with sand or air? Why?
Is this correct: both will hit the ground at the same time because the acceleration caused by gravity is constant. The mass doesn't affect which one will hit first. Both objects have the same surface area so air resistance doesn't matter.
What would happen if she removes all the air from the atmosphere and repeats the experiment? Why?
The acceleration is still constant so they'll hit at the same time
are those answers correct???
