1. The problem statement, all variables and given/known data http://postimage.org/image/466vu4yvp/ http://postimage.org/image/opdrmlv5n/ There can be more than one right answer 2. Relevant equations α=Δv/ΔX v = v0 + αt 3. The attempt at a solution Im having difficulty understanding the upward acceleration vector. Because I set the +y direction as positive (up) and the +x-direction as positive (right). So I thought that if acceleration is up, it means that acceleration is positive so the velocity is increasing (just a vector that is the exact same as the Vo vector). I attempted to add the two vectors together (hypotenuse) and say that was the answer, but it was incorrect (45° angle vector).
