Question

Two manned satellites approaching one another at a relative
speed of 0.450 m/s intend to dock. The first has a mass of 4.50 ✕
10^{3} kg, and the second a mass of 7.50 ✕ 10^{3}
kg. Assume that the positive direction is directed from the second
satellite towards the first satellite.

(a) Calculate the final velocity after docking, in the frame of
reference in which the first satellite was originally at
rest.

(b) What is the loss of kinetic energy in this inelastic
collision?

J

(c) Repeat both parts, in the frame of reference in which the
second satellite was originally at rest.

Two manned satellites approaching one another at a relative
speed of 0.150 m/s intend to dock. The first has a mass of 4.50 ✕
103 kg, and the second a mass of 7.50 ✕ 103 kg. If the two
satellites collide elastically rather than dock, what is their
final relative velocity? Adopt the reference frame in which the
second satellite is initially at rest and assume that the positive
direction is directed from the second satellite towards the first
satellite....

Two manned satellites approach one another at a relative speed
of 0.550 m/s, intending to dock. The first has a mass of 2.00 ✕ 103
kg, and the second a mass of 7.50 ✕ 103 kg. If the two satellites
collide elastically rather than dock, what is their final relative
velocity in meters per second? (Adopt the reference frame in which
the second satellite is initially at rest and assume that the
positive direction is directed from the second satellite...

Two manned satellites approach one another at a relative speed
of 0.250 m/s, intending to dock. The first has a mass of 2.50 ✕
103 kg, and the second a mass of 7.50 ✕ 103
kg. If the two satellites collide elastically rather than dock,
what is their final relative velocity in meters per second? (Adopt
the reference frame in which the second satellite is initially at
rest and assume that the positive direction is directed from the

velocity, in meters per second, of the cars.
Part (b) Calculate the direction of the final
velocity, in degrees south of west, of the cars.
Part (c)...

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1250 kg and is approaching
at 9.5 m/s due south. The second car has a mass of 550 kg and is
approaching at 17 m/s due west.Calculate the direction of the final
velocity, in degrees south of west, of the cars.What is the change
in kinetic energy, in joules, for the collision? (This energy goes
into deformation of the cars.)
