 P: 6 1. The problem statement, all variables and given/known data How far does the runner whose velocity-time graph is shown in Fig. 2-30 travel in 10 s? 2. Relevant equations x = v0t + 1/2at^2 3. The attempt at a solution x = 10s (0) + 1/2(8m/s)(10s)^2 x = 400m
 Sci Advisor HW Helper P: 3,031 The x = . . . equation you wrote is relevant to the problem, but there are other relationships involving velocity and time that are more directly useful in this problem. The fact that you are given a graph suggests that the problem is looking for one such relationship in particular. Can you say what it is?
 HW Helper P: 3,220 Hint: the displacement from t = 0 to some time t1 equals the area under the v(t) graph from the points t = 0 to t1. Edit: late.
 Mentor P: 8,325 Velocity-time graph question There's an easier method to use here, since you are given a graph. Do you know a way to find the distance from a velocity time graph? edit: haha, even later!
