Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 900 kg. The satellite is initially at position <3.8, -1.2, 2.2> m and has a speed of 6 m/s. You exert a force <-500, 500, 350> N. When the satellite reaches the position <2.7, 3.3, 0.4> m, its speed is 5.75 m/s. How much work did your friend do

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
