Objective function for projectile

I have a function to calculate projectile's distance and velocity in both x and y direction. I need to write a function, which defines the objective function to be minimised. objective should take as arguments: the two variables being optimised (i.e. the initial velocity and angle), and the target coordinates tx and ty. It should call my function mentioned earlier with the initial conditions and return the shortest distance between the computed trajectory and (tx, ty). I've not dealt with optimization before so I don't know where to start.

Many thanks

My demo calculates those but I don't use optimization. What are you varying to get your optimization.

My demo is attached.

Seems to be a homework exercise.
