Suppose an arrow is shot upward with a velocity of 65 feet per second, then its height in feet after t seconds is given by h(t) = 65t - 16t2. Round your answers to four decimal places. a) Find the average velocity of the arrow over the given time intervals. [7, 7.1]: ft/sec [7, 7.01]: ft/sec [7, 7.001]: ft/sec b) Estimate the instantaneous velocity when t = 7. ft/sec Question Help: Video Submit
