An object thrown at 159 vertical feet per second from a height of 99 ft has a height modeled by, h(t) = - 16t2 + 159t + 99 Where h(t) is the height of the object (in feet) t seconds after it was thrown. a) Find the average velocity of the object between 8.999 seconds and 9 seconds. ft per second (round to two decimal places) b) Find the average velocity of the object between 9 seconds and 9.001 seconds. ft per second (round to two decimal places) c) Using the above average velocities around 9 seconds, estimate the instantaneous velocity at 9 seconds. ft per secondf(z) = V16 - 22 f () represents the position of an object for time x. Find the average velocity over the the interval [1, 4]. Round your answer to four decimal places.For each value below, enter the number correct to four decimal places. Suppose an arrow is shot upward on the moon with a velocity of 37 m/s, then its height in meters after t seconds is given by h(t) = 37t - 0.83t2. Find the average velocity over the given time intervals.
