Step 4 Next, for the time period [1, 1.01], we have the following. Vava = 3.28 - 1.86(0.01) 3.26 3.26 m/s (rounded to two decimal places) And finally, for the time period [1, 1.001], we have the following. avg = 3.28 - 1.86 0.001 .001 3.28 3.28 m/s (rounded to two decimal places) Step 5 (b) Use your answers from part (a) to estimate the instantaneous velocity of the rock when t = 1. To estimate the speed when t = 1, we need to estimate Vaya = 3.28 - 1.86h when h approaches X . This yields the following. Enter an exact number. Vavg m/s Submit Skip (you cannot come back)
