So for Klingon I used sf = si + v(tf - ti) and got the sf equals 211.2 Then using that and the equation sf = si + vi(tf-ti) + .5a(tf-ti)^2 and solved for a getting -.221. When I put that in as an answer i am told it is wrong. What am i still doing wrong here?

Thank you so much. That worksed perfectly now.
