Chapter 2, Problem 30(choose chapter or problem)
A child inflates a balloon, admires it for awhile and then lets the air out at a constant rate. If V (t) gives the volume of the balloon at time t, then Figure 2.27 shows V (t) as a function of t. At what time does the child: (a) Begin to inflate the balloon? (b) Finish inflating the balloon? (c) Begin to let the air out? (d) What would the graph of V (t) look like if the child had alternated between pinching and releasing the open end of the balloon, instead of letting the air out at a constant rate?
