A satellite has a mass of 5825 kg and is in a circular orbit 4.34 × 105 m above the surface of a planet. The period of the orbit is 2.3 hours. The radius of the planet is 4.81 × 106 m. What would be the true weight of the satellite if it were at rest on the planet's surface?
find the combined mass of the dog and basket. chandelier with mass is attached to the ceiling of a large concert hall by two cables.
You have a string with a mass of 14.1 g. You stretch the string with a force of 8.63 N, giving it a length of 1.93 m. Then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its f..
A high-speed flywheel in a motor is spinning at 450 rpm when a power failure suddenly occurs. The flywheel has mass 37.0kg and diameter 71 cm. The power is off for 27.0s and during this time the flywheel slows due to friction in its axle bearings...
