A spaceship is orbiting the Earth at a certain height above the surface of the Earth at a certain orbital speed. The spaceship then attempts to reach escape speed to reach a distant planet. If the orbital speed is 28,500 km/h, what escape speed is necessary? Give your answer to the nearest hundred (100) km/h. Do not give units in your answer. The gravitational force between two objects is 180 N. If the distance between them is tripled, the new force between them will be: 1620 N 90 N 20 N 60 N 540 N A horizontal 52.0-N force is needed to slide a 50.0-kg box across a flat surface at a constant velocity. What is the coefficient of kinetic friction between the box and the floor?
