(a) Find the average velocity (in m/s) over the given time intervals. Recall that the average speed between times t, and t, is calculated using the following y (t2 ) - y(t 1 ) Vavg to - t1 We are given that y = 7t - 1.86t2. Evaluating at t = 1, we have y(1) = 7(1) - 1.86(1)2 = 5.14. Thus, the average speed between times 1 and 1 + h is as follows. Vava y(1 + h) - y(1) (1 + h) -1 7 ( 1 + h ) - 1.86 (1 + 1 ) 2 - 5.14 h 3.28h - 1)12 h Submit Skip (you cannot come back)
