Aperson is standing a distance d = 5.8 m in front of a flat, vertical mirror. the distance from the ground to his eyes is h = 1.6 m. an object is placed on the ground a distance d = d/2 = 2.9 m in front of the mirror. at what height h should the bottom of the mirror be so that the person can see the bottom of the object?

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
