darth vader's answer as a negative 21.2 (-21.2 m/s) was properly calculated
I was looking at it as solved correctly depending on point of view for upward being positive or negative. However, after re-reading the problem, it uses a 4m/s as the initial velocity of the bear so considering up to be negative velocity could be considered incorrect. I'll give you that one but if I was the teacher, I'd give either one credit for knowing how to do it.
