1. The problem statement, all variables and given/known data 2. Relevant equations D=VΔt Vf=Vi+ayΔt Df=Di+VyΔt+(1/2)ayΔt2 3. The attempt at a solution I solved for d using 1/2ayΔt2 and got 10.30m (Solving for d is a question later on in this assignment and i checked it there and it is incorrect...) Then I used Df=Di+VyΔt+(1/2)ayΔt2 but every time I try this equation I get the wrong answer because I am unable to calculate d correctly... I'm not sure if I'm stuck because I can't get d right and need d for Vxinitial or if I'm just going about solving for Vxinitial all wrong.
