    Can you deduce the coefficient of restitution from impace force plot?

    can anyone help me with a last effort? thanks, kwan

    Can you deduce the coefficient of restitution from impace force plot?

    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.

    Can you deduce the coefficient of restitution from impace force plot?

    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...

    Can you deduce the coefficient of restitution from impace force plot?

    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...

    Can you deduce the coefficient of restitution from impace force plot?

    hopefully somebody can help me out before my final tomorrow, thanks guys

    Can you deduce the coefficient of restitution from impace force plot?

    hmm it gives us the impulse (Newton*Seconds) but can the coeff. of restitution be deduced from that? i am still kind of lost unfortunately

    Can you deduce the coefficient of restitution from impace force plot?

    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...
