34. (a) By Eq. 9-30, impulse can be determined from the “area” under the F ( t ) curve. Keeping in mind that the area of a triangle is 1 2 (base)(height), we find the impulse in this case is 1.00 N . s. (b) By definition (of the average of function, in the calculus sense) the average force must be the result of part (a) divided by the time (0.010 s).

Unformatted text preview: Thus, the average force is found to be 100 N. (c) Consider ten hits. Thinking of ten hits as 10 F ( t ) triangles, our total time interval is 10(0.050 s) = 0.50 s, and the total area is 10(1.0 N . s). We thus obtain an average force of 10/0.50 = 20.0 N. One could consider 15 hits, 17 hits, and so on, and still arrive at this same answer....
