Asatellite has a mass of 4050 kg and is in a circular orbit 9.45 x 105 m above the surface of a planet. The period of the orbit is 2.18 hours. The radius of the planet is 8.77 x 106 m. What is the true weight of the satellite when it is at rest on the planet's surface? Number n Units v A 30-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, her kinetic energy decreases to 230 J from 410 J. How high does she rise during this interval? Neglect air resistance. Number n Units v A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.73 m. With the string hanging vertically, the object is given an initial velocity of 1.3 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point Where the string makes an angle Gwith its initial vertical orientation and then swings back downward. Find the angle 9. Number n Units v
