Due in 10 Minutes PART TWO (Two balls dropping from roof) True/False

• FAJISTE
In summary, when two balls are dropped from the same building, with the same acceleration and ignoring air resistance, the following statements are true: the difference between their accelerations stays the same, ball A will hit the ground before ball B, both balls have the same vertical acceleration, and the distance between them decreases as time progresses.

Due in 10 Minutes PART TWO ! (Two balls dropping from roof) True/False

Homework Statement

Ball A is dropped from the top of a building. One second later, ball B is dropped from the same building. Consider the balls while they are both in flight. You may ignore air resistance. Which statements are true about this situation?
As time progresses, the difference between their accelerations increases
Ball A will hit the ground before ball B
Both have the same vertical acceleration
As time progresses, the difference between their velocities increases
As time progresses, the distance between them stays constant

The Attempt at a Solution

1. False, acceleration is constant 9.81
2. True, it fell first
3. True, acceleration is constant
4. Hm. I say true? One started accelerating first so the velocity should increase faster than the other
5. False, wouldn't it increase because the velocity on one is greater?Please help!

Again, you need to show working and not just guess the answers!

Done. Quick! Help! hehe

#4 - they have the same acceleration (you said this yourself), so why should A's velocity increase at a greater rate (i.e. have greater acceleration) if they're supposed to be the same?

1. Is it possible for both balls to hit the ground at the same time?

Yes, it is possible for both balls to hit the ground at the same time if they are dropped from the same height and there is no air resistance.

2. Does the weight of the balls affect their speed of falling?

No, the weight of the balls does not affect their speed of falling. According to the law of gravity, all objects will fall at the same rate regardless of their weight.

3. Will the ball with more mass reach the ground faster?

No, the mass of an object does not affect its speed of falling. As long as there is no air resistance, both balls will reach the ground at the same time.

4. Does air resistance play a role in this experiment?

Yes, air resistance can affect the speed at which an object falls. However, in this experiment, we assume there is no air resistance.

5. What other factors can affect the outcome of this experiment?

Other factors that can affect the outcome of this experiment include the height from which the balls are dropped, the shape and size of the balls, and external forces such as wind or air currents.
