As you stand on the sidewalk outside an apartment building, a 2.0-kg bird flies toward you at 3.5 m/salong a straight line that passes 3.0 m above your head and runs parallel to the street. a friend is reclining with his head 4.0 m directly above your head, watching from a balcony. what angular momentum do you observe the bird to have, using your head as a reference point? what angular momentum does your friend observe the bird to have, using his own head as a reference point?

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
