So I'm having an extremely hard time with problems like this. It gives two graphs, Vx Vy and you can figure out the slope of those two. V=Sqrt(Vx^2 + Vy^2) and deriving that gives you the magnitude of the acceleration. However, with Vx=-2t Vy=t I should get 5t over Sqrt (5t^2) but the answer given on the site is -10-10/10 = 2. It seems like the textbook is asking us to take a exponential leap off a cliff of understanding to somehow. Can someone give me a step by step process for solving these correctly, obviously its some process that's completely different from the steps used in a math class.
