A window washer sits in a bosun's chair that dangles from a massless rope that runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is m= 93.0 kg. With what magnitude of force F, must he pull downward to raise himself at constant speed? A spy satellite is needed to gather intelligence on two cities near the equator, City 1 at longitude 25.5° and City 2 at longitude 127°. The satellite has a mass of 1, 240 kg and will have to pass over each city in its orbit. The figure shows the cities and the satellite on a top view of Earth (that is, looking down on the North Pole). The arc angle between the two cities is simply the difference in their longitudes. There can be no more than 6 h of travel time for the satellite to traverse the minor arc of is orbit between the two cities. The radius RE of Earth is 6378100 m and the gravitational constant G is 6.673 x 10-¹1 m³/(kg-s²). Assuming that the satellite orbits Earth in the same direction that Earth rotates, at what maximum altitude can the satellite be positioned to satisfy these requirements?
