Projectile Motion Calculations: C Program and Coordinates

This assignment presents a C program designed to calculate projectile motion. The program takes user inputs for velocity, angle, and time, and then calculates the Cartesian and Polar coordinates of the projectile. The code includes necessary libraries and functions to perform the calculations, providing a practical example of applying physics principles in a programming context. The program is designed to help students understand the concepts of projectile motion and coordinate systems, making it a valuable resource for physics and programming students. This assignment is available on Desklib, a platform that offers AI-based study tools for students.
