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 < 4.0, -1.4, 3.0 > m and has a speed of 5 m/s. You exert a force < -400, 300, 300 > N. When the satellite reaches the position < 2.8, 2.2, 4.8 > m, its speed is 6.17 m/s. How much work did your friend do?
Work done by friend = J
