1. The problem statement, all variables and given/known data Al and Bert are jogging side by side on a trail in the woods at a speed of 0.75 m/s. Suddenly, Al sees the end of the trail 35 m ahead and decides to speed up to reach it. He accelerates at constant rate of 50 m/(s^2) while Bert continues on at a constant speed. (a) How long does it take Al to reach the end of the hill? Part (a) is the one I'm having trouble understanding. 2. Relevant equations Δx = (1/2)at^2 + Vt + X 3. The attempt at a solution 35 = (1/2)(0.50)t^2 + (0.75)t 35 = (0.25)t^2 + (0.75)t 35 = t[(0.25)t + 0.75] 35/t = (0.25)t + 0.75 And, that is where I stopped. I'm sure I pretty much went wrong at the third step.
