Collision of a Ball with a Barbell and Related Impulse Problems
Mungan, Carl E.
European Journal of Physics, v28 n3 p563-568 May 2007
The collision of a ball with the end of a barbell illustrates the combined conservation laws of linear and angular momentum. This paper considers the instructive but unfamiliar case where the ball's incident direction of travel makes an acute angle with the barbell's connecting rod. The analysis uses the coefficient of restitution generalized to extended objects (in contrast to the usual point particles of introductory physics). The treatment becomes a springboard to studying impulsive two-dimensional collisions between other rigid objects. (Contains 2 figures.)
