(a) Redo Example 8.7 to find an algebraic solution for d in terms of M, m, (s, L, and q. (b) Use this expression to show that placing the ladder at a larger angle q (that is, more nearly vertical) enables the person to climb farther up the ladder without having it slip, all other things being equal.
(c) Using the numerical values from Example 8.7, find the minimum angle q that enables the person to climb all the way to the top of the ladder.
