A 875-kgkg two-stage rocket is traveling at a speed of 6.80×103 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 2.40×103 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?

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. speed of...

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. larger velocity? smaller velocity?
