Mind boggling solutions!

The book is filled with simple and smart solutions. It many times, saved me from tedious integration. Diagrams are so illustrative that you can imagine the solution from it. By solving problems like 1.12, 1.13, and 1.16, I got the feel of what approach velocity is. One of the areas that troubled me was projectile motion but the 1.29 is such an enlightening problem that I am able to solve ANY problem in projectile motion now. These concepts are newly engrained in my head. After learning the solution of problem 1.33, I had my Eureka moment! No book explains that one better. Problem 1.106 was the real test of my fundas, the solution provided is extremely beautiful. No book or teacher can explain motion in a vertical circle as in 1.85. I can now imagine and visualize the problem before even touching the pen. Problem 1.81 makes all concepts of mechanics clear. This single problem is a life saver.
My physics sir solved these problems in class, but it was very lengthy ( 3 page solution). The author has done it in half page. Brilliant book and smartest solutions!
