Free-fall Problem: Ball 2 Thrown Upward with Gravity - Homework Solution

[nukeman]

Homework Statement

I am just trying to get confirmation I am correct. Refer to the picture below, which shows the question and diagram.

I am working on 2, a)

Homework Equations

The Attempt at a Solution

So I am to draw for ball 2 as if I was throwing the ball upwards against gravity.

Now, would my line and points be the same as Ball 1, just flipped over? Any help on this question(2,a) would be great!

Does the following picture give you a clue?

Spinnor, the question is not asking to draw the points as if the ball bounced, but insted launched from t = 0

From what I understand, it would look the same, in terms of the points correct?

Thanks anyone for the help!

Can anyone else take a crack at it? Much appreciated, thanks!

Again... I am having troubles with 2, a) and b)

 

[Spinnor]

Draw the same set of points on the right and start at the bottom and number them 1,2,3,4,5. Once you do this you should be able to do the rest. They don't meet half way up, with a little thought you should come up with the answer.

Hey,

So would they meet between the 2nd and 3rd point?Can you help me out with this "Which ball has traveled further and why?"

My guess would be ball 2 because its initial acceleration is greater ?
