in C language

2. [15 marks] A student wants to develop a program that will help solve various physics problems. Create a library of functions (header file and source file) that can be used to calculate the following quantities: a) Sin - a function that returns the sine of an angle o given in degrees, b) Momentum - functions that returns the x and y components of the momentum of an object, given the mass and velocity (magnitude and angle in degrees). c) Kinetic Energy - a function that returns the kinetic energy of an object, given the mass and speed. d) Gravitational potential - a function that returns the gravitational potential energy of an object, given the mass and height above the ground. The standard C library, math.h, already contains the functions for sin, cos and tan, however, these functions require the angle to be given in radians, double sin (double x), where x is the angle in radians. You are allowed to use these functions from the math.h library to help define your degree-based trigonometric functions. Make sure you use function and variable names that enhance readability. Remember to add any necessary #include directives. Add comments to describe your files and functions. Try to create efficient code. Note, your file should NOT have any printf() or main() in your source code
