- A ball traveling in a circle with a constant speed of 3.6 m/s has a centripetal acceleration of 7.0 m/s2. What is the radius of the circle? (Answer in meters.)Whenever two Apolloastronauts were on the surface of the Moon, a third astronaut orbited the Moon. Assume the orbit to be circular and 397 km above the surface of the Moon, where the acceleration due to gravity is 12 m/s2. The radius of the Moon is 1.70 ✕ 106 m. Determine the astronaut's orbital speed. Determine the period of the orbit.The orbit of Earth’s moon has a period of 27.3 days and a radius (semi-major axis) of 2.57 ×10-3 A.U. = 3.85 × 105 km. What is the mass of Earth? What are the units?
- According to Lunar Laser Ranging experiments the average distance LM from the Earth to the Moon is approximately 3.85 x 105 km. The Moon orbits the Earth and completes one revolution in approximately 27.5 days (a sidereal month). a) Calculate the orbital velocity of the Moon. b) Calculate mass of the Earth.The moon completes one (circular) orbit of the earth in 23.7 days. The distance from the earth to the moon is 3.84×10^8m. What is the centripetal acceleration of the moon?An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1810 × 103 seconds (about 21 days) on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 255.0 × 106 m and the planet has a radius of 3.30 × 106 m, calculate the moon's radial acceleration ?c.
