the largest airplane every build is the hughes h-4 hercules flying boat its 97.5 m wingspan is still 9.1 longer than the next largest plane ever to be built however because it is made of birch not spruce as its populare nickname the spruce goose would suggest the mass of the h-4 is 1.81 x 10^5 kg considerably lighter than any other giant plane. The h-4 was flown only once over a distance of about 1.6 km if the maximum gravitational potential energy associated with the h-4 was 3.78 x 10^7 j how high did it fly

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
