Question
A day on Mars is 88.6 times 103 s (about 40 min longer than a day on Earth). You are interested in studying a specific location on the surface of Mars, so you place a satellite in a "mars-o-synchronus" orbit; that is, as the satellite orbits Mars it is always directly above the location of interest. Calculate the radius of the orbit (from the center of Mars to the satellite). The mass of Mars is MM = 6.42 times 10 kg. at 8.0 m/s in the same direction. The gliders are of equal mass. After the collision it is observed that glider B is travelling at 10.0 m/s. What is the final speed of glider A? Is the collision elastic? The drawing shows a graph of the displacement x versus time t for an object on a horizontal spring. The equilibrium position is at x = 0 and there are no forces in the x-direction except for the spring. Which one of the following answers correctly give the magnitude v of the block's velocity and the magnitude F of the restoring force at points A and B on the graph? 12. A 3.00-kg model airplane has velocity components of 5.00 m/s due east and 8.00 m/s due north. What is the plane's kinetic energy?Explanation / Answer
