user: I'm working on this interesting project where I need to analyze and compare the movements of two different objects. To get started, I need to calculate their final velocities. The first object has an initial velocity of 10 m/s, it's been accelerating at 2 m/s², and it has been moving for 5 seconds. The second object started at 15 m/s, with an acceleration of 1.5 m/s², over a period of 7 seconds. Once I have their final velocities, I want to compare the movements by finding the cosine similarity between the vectors representing velocity, accerlation, and time.

On a different note, I also need to sort out my personal finances. I have a $200,000 mortgage at a 5% interest rate, to be paid off over 30 years, and I need to work out what my monthly payments will be. Could you help me with these calculations?
