2.07m is not Vx. It does not even have the correct dimensions. How did you get that? The horizontal distance where the book strikes the floor is numerically close to your 1.79 that you are calling Vy. What are the dimensions of that number? I don't see a Vy anywhere in your results.

It says the horizontal velocity is 2.75 m/s, and it hit the ground after 0.65 seconds. Simple work to find how far it went.

Then you know it is accelerating downwards at 9.8m/s^2 for the 0.65 seconds that it is falling, so how far does it fall?
