Thank you so much for the answer! I really appreciate you taking your time to help me. If I understand you correctly, ##\frac{\mid v_1 \mid}{2}## is the average speed going from touching the ground to being still? (And the same with the other average speed). Is the average speed calculated by...

I will be going over the experiment tomorrow afternoon, so I will make sure to check back with the complete calculation and answer :)

We did this experiment in class, and we were told to calculate the impulse and the time the ball touches the ground. The equipment we received was: a large ruler, stopwatch, powder, ball, way of measuring the radius (smaller, more exact instrument), and a scale. Although now that I think of it...

Oh ok, it's a shame our physics teacher didn't say anything about that. I suppose you would complete a number of different drops from different heights to determine it?

Do you have any example of such a function? I am getting kind of frustrated here over this experiment... :P

Hmm... yes that certainly would make things a lot easier. Although because I was not given any information regarding that I do not think that is how I'm supposed to solve it.

Another thing I thought about was that since we now know that the impulse is negative, that means that the average force also has to be negative, since it isn't reasonable to use a negative value for ##t## in ##I = Ft## ?

I think I understand what you are saying, and the part about the response force I recognize from my lessons. Although in this particular experiment I do not think that you need the constant you are talking about to solve the problem, atleast from my understanding of the lesson and the...

Thanks for taking the time to reply, and thanks to your explanation of why the impulse became negative I now understand. I do not know if the ball would be elastic. That means that it doesn't lose energy and momentum during the collision? But I think it does, since it doesn't reach the same...

I would like to start off by excusing myself in advance for not knowing all of the correct terminology, since I am not studying physics in English. 1. Homework Statement A ball is dropped from a certain height, it then falls down towards the ground and consequently bounces up again to a...
