Two Earth satellites, A and B, each of mass mmm = 930
kgkg , are launched into circular orbits around the Earth's center.
Satellite A orbits at an altitude of 4000 kmkm , and satellite B
orbits at an altitude of 12600 kmkm
What are the potential energies of the two satellites? (in
Jules)
What are the kinetic energies of the two
satellites? (in Jules)
How much work would it require to change the orbit of satellite A
to match that of satellite B? (in jules)
hint this is tricky problem

Two Earth satellites, A and B, each of mass m, are to be
launched into circular orbits about Earth's center. Satellite A is
to orbit at an altitude of 6820 km. Satellite B is to orbit at an
altitude of 18100 km. The radius of Earth REis 6370 km. (a) What is
the ratio of the potential energy of satellite B to that of
satellite A, in orbit? (b) What is the ratio of the kinetic energy

Two satellites, A and B, both of
mass m = 115 kg, move in the same circular orbit of radius r = 7.57
106 m around Earth but in opposite senses of rotation and therefore
on a collision course.
a) What is the total mechanical energy EA +
EB of the two satellites +
Earth system before the collision?
b)If the collision is completely inelastic so that the wreckage
remains as one piece of tangled material (mass = 2m), what...

Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 458 km above the earth’s
surface, while that for satellite B is at a height of 732 km. Find
the orbital speed for (a) satellite A and
(b) satellite B.
can two satellites with different masses have the same orbit around the earth?

Two projectiles with 50kg mass each are launched in opposite
directions towards each other, both at an angle of 30 degrees off
the horizontal. They both have the same initial velocity of 75m/s
and they are separated by a distance of 200m.
a.) What is their combined initial kinetic energy?
b.) Right before they collide, how high off the ground are
they?
c.) What is their total momentum here? (both directions)
d.) When they collide they stick together and lost...

Schweser Satellites Inc. produces satellite earth stations that
sell for $105,000 each. The firm's fixed costs, F, are $2 million,
50 earth stations are produced and sold each year, profits total
$500,000, and the firm's assets (all equity financed) are $6
million. The firm estimates that it can change its production
process, adding $3 million to assets and $310,000 to fixed
operating costs. This change will reduce variable costs per unit by
$12,000 and increase output by 22 units. However,...
