Normal and tangential coordinates with cartesian frame

A package is dropped from the plane which is flying with a constant horizontal velocity of V_A=150 ft/s. Determine the normal and tangential components of acceleration and the radius of curvature of the path of motion (a) at the moment the package is released at A and (b) just before it strikes the ground at B.

I'm Cherish! I currently teach Mechanical Engineering at a University but I remember the days of being a struggling engineering student. Going to class, feeling confused and frustrated when trying to do assignments because I hadn't learned much in class seemed to be a regular occurrence. I created STEM Course Prep to save today's engineering students from the same fate. I teach my courses in a way I would have liked to be taught... light on theory, heavy on examples. Organization is key to learning so I also provide an outline of notes for my courses so you can stay organized and create a great resource for each course.
