An earth satellite remains in orbit at a distance of 14315 km from the center of the earth. What is its period? The universal gravitational constant is 6.67×10−11 N·m2/kg2 and the mass of the earth is 5.98×1024 kg. Answer in units of s.
What is the magnitude of the gravitational force between the Earth and the Hubble Space Telescope (HST), which orbits the Earth? Assume the distance from the center of the Earth to the HST is 6,930 km, the mass of the Earth is 5.97 x 1024 kg, the mass of the HST is 1.11 x 104 kg, and G=6.67 x 10-11 Nm2/kg2.
A satellite orbits the earth at a distance of 12,000 km from the earth’s center. At this distance the force of gravity on the satellite is 900N. What would the force on the satellite be if the distance were 8000 km instead? For the previous problem, find the speed of rotation of the satellites. The mass of the Earth is 6 x 1024 kg, and G = 6.67 x 10-11 Nm2 /kg2 .
The distance between an artificial satellite and the center of the Earth is 4.50×107 m. The mass of the satellite is 450 kg and that of the Earth is me = 5.98×1024 kg. The gravitational constant G = 6.67×10-11Nm2/kg2. (a) Use Newton's law of the gravitational force to find the force between the satellite and Earth. (b) Is this force an attractive force or a repulsive force?
A satellite of Earth is moving in a circular orbit with Earth at its center, at a constant speed of 2.00 km/s. a.) How high is the satellite above the surface of the Earth? b.) How long does it take for the satellite to complete one revolution? Helpful info (but not all of it is relevant!): universal gravitational constant G is = 6.674 x 10^-11 m^3/kg s^2 (units may also be expressed as N m^2/kg^2) Mass of Sun = 1.989...
A satellite m = 500 kg orbits the earth at a distance d = 218 km, above the surface of the planet. The radius of the earth is re = 6.38 × 106 m and the gravitational constant G = 6.67 × 10-11 N m2/kg2 and the Earth's mass is me = 5.98 × 1024 kg. What is the speed of the satellite in m/s?
The mass of the sun is 1.99×1030kg and its distance to the Earth is 1.50×1011m. What is the gravitational force of the sun on the earth?
Find the speed of a satellite in a circular orbit around the Earth with a radius 2.77 times the mean radius of the Earth. (Radius of Earth -6.37x103 km, mass of Earth 5.98x1024 kg, G - 6.67x10 11 Nm2/kg2.)
A satellite is in a circular orbit about the Earth at a distance of four (4) Earth radii above the surface of the Earth. What is the velocity of the satellite? (Earth's mass: ME = 5.98 x 1024 kg; the radius of the Earth: 6.4 x 106m ; G = 6.67 x 10-11 Nm2/kg2 ). A) 4,072.5 m/s B)3,530.5 m/s C)5,582.2 m/s D)7,465.9 m/s
I need some help with these final problems please!
9. (a) Find the centripetal acceleration on a 2000 kg car travelling with a speed of 25 mph around a curve of 35 m. A banked curve makes an angle of 30° with the horizontal. Find the centripetal acceleration of this banked curve. (b) 10. (a) Find the force of attraction between the earth and the sun using the Newton's law of Universal Gravitation and the following: Mass of the earth...
