Question

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?

Answer #1

A 780-kg two-stage rocket is traveling at a speed of 6.90×103
m/s away from Earth when a predesigned explosion separates the
rocket into two sections of equal mass that then move with a speed
of 2.50×103 m/s relative to each other along the original line of
motion. a.)What is the speed of each section (relative to Earth)
after the explosion? Express your answers using three significant
figures separated by a comma. b.)What are the direction of each
section (relative to...

A 740-kg two-stage rocket is traveling at a speed of 6.40×10^3
m/s away from Earth when a predesigned explosion separates the
rocket into two sections of equal mass that then move with a speed
of 2.30×10^3 m/s relative to each other along the original line of
motion.

A
795 kg two-stage rocket is traveling at a speed of 6.90×10^3 m/s
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 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.
larger velocity?
smaller velocity?

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 37.0-kg body is moving in the direction of the
positive x axis with a speed of 243 m/s when,
owing to an internal explosion, it breaks into three pieces. One
part, whose mass is 10.0 kg, moves away from the point of
explosion with a speed of 397 m/s along the
positive y axis. A second fragment, whose mass is 3.5 kg,
moves away from the point of explosion with a speed of 337
m/s along the negative x...

A 41.0-kg body is moving in the direction of the positive x axis
with a speed of 283 m/s when, owing to an internal explosion, it
breaks into three pieces. One part, whose mass is 5.0 kg, moves
away from the point of explosion with a speed of 408 m/s along the
positive y axis. A second fragment, whose mass is 2.5 kg, moves
away from the point of explosion with a speed of 316 m/s along the
negative x...

A ball with mass M = 5 kg is moving with speed V=10 m/s and
collides with another ball with mass m = 2.5 kg which is initially
stationary. There is no other force such as gravity acting on the
two balls. After the collision, both balls move at angle θ=30
degrees relative to initial direction of motion of the ball with
mass M = 5 kg. a) What are the speeds of the two balls after the
collision? b)...
