Is it just me or is this book complete ****? I've only read the second chapter on velocity and acceleration but it's horrible. The examples use algebraic formulas and are nothing like the assigned problems. I remember one the questions asks to find the initial velocity and initial position of a function [itex]x(t)=a + b\cdot t - c\cdot t^2[/itex], where a is initial position, b is initial velocity, and c is initial acceleration. The book doesn't mention what a, b, and c are. Instead, it's left up to the reader to magically figure it out? I don't know how a student can be expected to learn from this textbook when everything is obtuse.
