Question

A 875-kgkg two-stage rocket is traveling at a speed of
6.80×10^{3} m/sm/s away from Earth when a predesigned
explosion separates the rocket into two sections of equal mass that
then move with a speed of 2.40×10^{3} m/sm/s relative to
each other along the original line of motion.

-What is the speed of each section (relative to Earth) after the explosion?

-How much energy was supplied by the explosion? [*Hint:*
What is the change in kinetic energy as a result of the
explosion?

away from earth when a predesigned mass that then move with a speed
of 2.38×10^3 m/s relative to each other along the original line of
motion. How much energy was supplied by the explosion?

A 5 kg missile is traveling at a speed of 70 m/s away from the
testing facility when a predesigned explosion separates the missile
into two sections of equal mass that then move with a speed
of 30 m/s relative to each other along the original line of
motion.
a. What is the speed of each section after the explosion
relative to the testing facility?
b. How much energy was supplied by the explosion?

The last stage of a rocket is traveling at a speed of 17,000 mph
(25,000 ft/sec). This last stage is made up of two parts which are
clamped together, namely, a rocket case with a mass of m1 =20 slugs
and a satellite with a mass of m2 =10 slugs. When the clamp is
released, a compressed spring causes the two parts to separate with
a relative speed of 3000 ft/sec. (a) What are the speeds of the two
parts...

PLEASE SHOW WORK! A 4 kg body is traveling at 3
m/s with no external force acting on it. At a certain instant an
internal explosion occurs, splitting the body into two chunks of 2
kg mass each. The explosion gives the chunks an additional 18 J of
kinetic energy. Neither chunk leaves the line of original motion.
Determine the speed and direction of motion of each of the chunks
after the explosion. Hint: Translational momentum is conserved.

A 6.9 kg model rocket is traveling horizontally and due south
with a speed of 20.2 m/s when it explodes into two pieces. The
velocity of one piece, with a mass of 2.4 kg, is v1 = (-12 m/s)i +
(30 m/s)j + (15 m/s)k, with i pointing due east, j pointing due
north, and k pointing vertically upward.
(a) What is the velocity of the other piece, in unit-vector
notation? Incorrect: Your answer is incorrect. m/s i m/s j...

A body of mass 11.0 kg is traveling at 4.3 m/s
along the positive x-axis with no external force acting. At a
certain instant an internal explosion occurs, splitting the body
into two chunks of 5.5 kg mass each. The explosion gives
the chunks an additional 16 J of kinetic energy. Neither
chunk leaves the line of original motion. Determine the speed and
direction of motion of each of the chunks after the explosion.

A 0.00400-kg bullet traveling horizontally with speed 1.00 103
m/s strikes a 20.0-kg door, embedding itself 10.9 cm from the side
opposite the hinges as shown in the figure below. The 1.00-m wide
door is free to swing on its frictionless hinges. (a) Before it
hits the door, does the bullet have angular momentum relative the
door's axis of rotation? Yes No (b) If so, evaluate this angular
momentum. (If not, enter zero.) kg · m2/s If not, explain why...
