1. The problem statement, all variables and given/known data An object is thrown upwards vertically with an initial speed of a and an initial height of h. It travels for t seconds until it hits the ground with a speed of b. If a was 0.5a, what would the hang time be in terms of t? 2. Relevant equations xf=xo+vot+.5(-10)t^2 vf=vo+(-10)t 3. The attempt at a solution I tried to split up this problem into two parts: 1) object moving up 2) object moving down. But t is given as the time of the entire problem so I don't know how to split t up for the two parts.
