i am truly at a dead end. i do not see how one can get energy or velocity from this graph since multiplying force (N) times time (milliseconds) equals impulse.
i have been thinking and googling this question since i first posted and joined the forum hours ago. i am stuck.
the area of the first triangle is 10 and the area of the second is 5, the ratio is .5.
the slope of the first triangle is 5 and the slope of the second triangle is 10. the ratio is also .5.
so my questions is, is the coefficient of restitution .5? or am i missing something? or is it not...
i see now i am kind of getting it. yes the two slopes are different (and naturally the two areas under the graph as well, divided by the peak).
1) can we get a definitive quantitative answer using this graph for the coefficient of restitution?
2) if yes, would it be the ratio of the two...
If you have the impact force on the y-axis (in Newtons) and the time on the x-axis (in milliseconds), can you get the coefficient of restitution from just this? The plot is for the force of impact exchanged between two balls as a function of time.
I know the coefficient of restitution is the...
