Hello again, I was trying to find the Vy at .66s like you do shown in the quote above. When I do the calculation myself I get around -.93m/s

Also, will you explain what you did there?

What I see is this:

Vy-at

Where did you derive that equation from?

Sorry for all of the questions, I am just trying to see where I am missing something.

Thanks,

CC
