Dynamics book
Hi,
I have not read the book, either of them. But the first one which u hav written seems to be more of a School book, the topics are really basic. And the second one as the name suggests is engineering leve. So, my recommendation is that, if u r strong with the basics, then go with the 2nd one otherwise, start with the first one. Also, the topics in the first book were more similar to that of the mechanics topic covered in fundamentals of physics, resnick and halliday. so, that might also be of some use to u.
good luck,
cedance.
