The mass of Jupiter is 1.88x1027 kg and its radius is 7.18x107 m.  Find the acceleration due to gravity on Jupiter’s surface

Current Attempt in Progress A satellite is in a circular orbit about the earth (ME = 5.98 x 1024 kg). The period of the satellite is 2.11 x 104 s. What is the speed at which the satellite travels? V =

A hypothetical planet has a radius 1.6 times that of Earth but has the same mass. - What is the acceleration due to gravity near its surface?

The Earth exerts a gravitational force on the Moon, keeping it in its orbit. The Newton third law partner to this force is O The centripetal force on the Moon. O The ocean tides due to the Moon and the Sun O The gravitational force on the Earth by the Moon. The nearly circular orbit of the Moon around the Earth.

2) Base your answer to the question on the information below and on your knowledge of physics. A gas-powered model airplane has a mass of 4.50 kilograms. A student exerts a force on a cord to keep the airplane flying around her at a constant speed of 50.0 meters per second in a horizontal, circular path with a radius of 100 meters. Calculate the magnitude of the centripetal force exerted on the airplane to keep it moving in this circular path. [Show all work, including the equation and substitution with units. ]
