Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 900 kg. The satellite at position <3.9, -1.5, 2.0>m and has a speed of 5 m/s. You exert a force <-500, 500, 250> N. When the satellite reaches the position <2.9, 3.0, 0.2> m, its speed is 4.57 m/s. How much work did your friend do?
