Sally and Sam are in a spaceship that comes to within 17,000 km of the asteroid Ceres. Determine the force Sally experiences due to the presence of the asteroid. The mass of the asteroid is 8.7 1020 kg and the mass of Sally is 76 kg. For calculation purposes assume the two objects to be point masses

You are seated 1.5 m away from your best friend. One of you has a mass of 60 kg and the other has a mass of 70 kg. a) What is the magnitude of the gravitational force that each one of you exerts on the other? B) What is the direction of this force?

A distant planet with a mass of (2.800x10^26) has a moon with a mass of (9.0000x10^23). The distance between the planet and the moon is (8.8000x10^11). What is the gravitational force between the two objects? Note: Your answer is assumed to be reduced to the highest power possible.

Two books are on a shelf 1.3 m from one another. Book A has a mass of 2.2 kg. Book B hasa mass of 1.7 kg. An absentminded student picks up book A to see if it is useful for his re-search paper. He decides not to use the book and sets it on a shelf 1.8 m from book B.What effect does this have on the gravitational force between the books?AThe gravitational force remains the same because the masses of the books remainconstant.BThe gravitational force decreases because the distance between the books increases.The gravitational force increases because the distance between the books increases.DThe gravitational force remains the same because distance does not affect gravity for small objects

Two asteroids are separated by a distance in space. One asteroid collides with a cluster of smaller ones which increases its mass by 2½ times. In the process the distance between the two asteroids decreases by ⅔. What is the change in the gravitational force between them? Express you answer as a factor of the original gravitational force.

Find the distance of a point from the earth's center where the resultant gravitational field due to the earth and the moon is zero. The mass of the earth is 6 * 0 * 10 ^ 24 kg and that of the moon is 7*4*10^ 22 kg. The distance between the earth and the moon is 4*0*10^ 5 km.

Problem 9: A 3500-kg spaceship is in a circular orbit 180 km above the surface of Earth. It needs to be moved into a higher circular orbit of 390 km to link up with the space station at that altitude. In this problem you can take the mass of the Earth to be 5.97 x 1024 kg.

Pluto has at least four satellites, the largest of which is Charon. Charon orbits Pluto once every 6.387 days, and the semi-major axis of the orbit is 19 570 km. Find the sum of the masses of Pluto and Charon.

Let planet A have a mass of 5.44 x 1045 kg and planet B have a mass of 2.77 x 1033 If they are attracted by a gravitational force of 6.59 x 103 N, how far apart are their centers of mass

Two objects attract each other with a gravitational force of magnitude 9.00 10-9 N when separated by 19.9 cm. If the total mass of the objects is 5.08 kg, what is the mass of each? heavier mass answer in ___kg   lighter mass answer in ___kg
