(a) Take the slope of the curve in Figure 2.64 to find the jogger’s velocity at t = 2.5 s . (b) Repeat at 7.5 s. These values must be consistent with the graph in Figure 2.65.

Step-by-step solution 64PE Step 1 of 6 Refer the figure 2.64 and figure 2.65 provided in the textbook. The slope of the Position vs. time graph gives velocity. Step 2 of 6 The time and corresponding position from graph are tabulated below as, time (s) x (m) 0 0 2.5 10 5 17.5 7.5 10 10 2.5 12.5 2.5 15 5 20 25 Step 3 of 6 (a) The slope of the Position vs. Time graph is calculated by tangent drawn at time 2.5 s.
