Question

Two objects are floating in a region free of other gravitating bodies. The first object has a mass of 1.4x10^15kg and a radius of 19000m. The second object has a mass of 4.9x10^16kg and a radius of 13000m. They initially rest with a distance of 810000m apart.

A) Determine the force acting on each object initially

B) b/c their mutual gravitational attraction, the two objects will drift towards each other and collide. Determine the speed of each at the instant of collision.

Answer #1

two isolated objects moving with equal speeds coming
towards each other from the right and left collide. after the
collision the objects stick and drift left. what can be concluded
about the masses of the objects from an inertial frame

Two objects, one with a mass of 75.0kg and the other with a mass
of 60.0kg experience a gravitational force of attraction of
8.50x10-9N. How far apart are their centers of mass?

Two objects move towards each other along a straight line and
collide inelastically. It is known that the ratio of their kinetic
energies is n. What should be the ratio of their massess fo the
objects to move after the collision in the direction of motion of
the object with the smallest kinetic energy?
Please explain solutions.

One object is at rest, and another is moving. The two collide in
a one-dimensional, completely inelastic collision. In other words,
they stick together after the collision and move off with a common
velocity. Momentum is conserved. The speed of the object that is
moving initially is 30 m/s. The masses of the two objects are 3.0
and 7.6 kg. Determine the final speed of the two-object system
after the collision for the case (a) when the large-mass object is...

Two charged objects 1 and 2 are held at a distance r
apart. Object 1 has mass m and charge +3q, and
object 2 has mass 2m and charge +q. The objects
are released from rest. Assume that the only force exerted on
either object is the electric force exerted by the other
object.
Part B
When the objects are at a distance 4r apart, what is
the speed of object 1?
Part C
When the objects are at a...

Consider two objects which collide. The first object has a mass
of 1 kg which is moving with an initial velocity of 4 m/s to the
right. It hits a second object of 4 kg which is initially moving
with an initial velocity of 4 m/s to the left. After the collision,
the second object is moving 2 m/s to the left.
What is the final velocity of the first object? Show your
work.
a)2.82 m/s to the left
b)2.82...

An experiment is performed in deep space with two uniform
spheres, one with mass 20.0 kg and the other with mass 108.0 kg .
They have equal radii, r = 0.30 m . The spheres are released from
rest with their centers a distance 40.0 m apart. They accelerate
toward each other because of their mutual gravitational attraction.
You can ignore all gravitational forces other than that between the
two spheres.
A. When their centers are a distance 28.0 m...

An experiment is performed in deep space with two uniform
spheres, one with mass 28.0 kg and the other with mass 110.0 kg .
They have equal radii, r = 0.30 m . The spheres are released from
rest with their centers a distance 42.0 m apart. They accelerate
toward each other because of their mutual gravitational attraction.

Two asteroids in space that are near each other experience a
force of 5,107 N due to the gravitational force between
them. If their positioning was changed so that they were
spaced 2 times their original distance apart, what would the new
force of attraction between them be?
A Ferris wheel at a carnival has a radius of 12 m and turns so
