Write a program in Matlab to calculate the position of a projectile at a given time t. For the gravitational constant g and an initial velocity v and angle of departure , the position is given by x and y coordinates as follows:

x=vcos( )t

y=vsin()t-1/2 gt^2

The program should ask the user to input the initial velocity, time (>0), and angle of departure (in degrees: 0-360). All user input should have input validation. It should then call a function to find the x and y coordinates, and another function to print the results. Note: g=9.81
