1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution This is more of a help with understanding problem. I understand a) and b), but for c), I don't understand: 1. Why is the distance from t=12-16 -20 m and not +20 m? Isn't there a positive slope? I thought this question was asking for distance traveled, not displacement? 2. My attempt at c) was to use the equation y(t)-y0 = 1/2(v0+v(t))t, but my answer was 325 m. y0=+75 m, v0=20 m/s, v(t)=5 m/s, and t=20s. What did I do wrong?
