A 790-kg two-stage rocket is traveling at a speed of 6.60×103 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 2.80×103 m/s relative to each other along the original line of motion What is the speed of each section (relative to Earth) after the explosion? Express your answers using three significant figures separated by a comma. V1,V2= What are the direction of each section (relative...

A 720-kg two-stage rocket is traveling at a speed of 6.90×10^3 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 2.10×10^3 m/s relative to each other along the original line of motion.What is the speed of each section (relative to Earth) after the explosion? R/= v1=5850, v2=7950. How much energy was supplied by the explosion? [Hint: What is the change in kinetic energy as a...

In the first stage of a two-stage rocket, the rocket is fired from the launch pad...

In the first stage of a two-stage rocket, the rocket is fired from the launch pad starting from rest but with a constant acceleration of 3.50 m/s2 upward. At 25.0 s after launch, the second stage fires for 10.0 s, which boosts the rocket’s velocity to 132.5 m/s upward at 35.0 s after launch. This firing uses up all the fuel, however, so after the second stage has finished firing, the only force acting on the rocket is gravity. Air...

A two-stage rocket has a total initial mass with the fuel of 4.5x106 kg is docked at rest at a space station. A total of 2.3x106 kg of fuel is on board. The mission for the ship is to reach a planet that is located at a distance of 7.5x1010m away. The fuel is used at a constant rate of 800kg/s for both stages of the rocket. The exhaust velocity for the rocket's engines is 7500m/s (stage1) and 5000m/s (stage2)....

A Saturn 5 third stage rocket boosts Apollo 17 (46,768 kg, 103,106 lbs) from orbital speed...

A Saturn 5 third stage rocket boosts Apollo 17 (46,768 kg, 103,106 lbs) from orbital speed (7,822 m/s, 17,500 mph) to escape speed (11,174 m/s, 25,000 mph) to reach the moon. Determine the exhaust gas velocity needed for this "deltavee". Third stage booster mass by itself is 104,328 kg before and 11,249 kg after the rocket “burn”.

A rocket is launched straight up. It contains two stages (Stage 1 and Stage 2) of solid rocket fuel that are designed to burn for 10.0 and 5.0 s, respectively, with no time interval between them. In Stage 1, the rocket fuel provides a net upward acceleration of 18 m/s2. In Stage 2, the net upward acceleration is 13 m/s2. Neglecting air resistance, calculate the maximum altitude above the surface of Earth of the payload and the time required for...

A rocket of rest length 90 meters is traveling at speed 4/5c directly away from earth. The rocket encounters an asteroid of length 80 meters also travelling directly away from the earth but at speed 3/5c. a)According to the captain of the rocket, what is the velocity of the rocket relative to the asteroid? b)At the front of the rocket, the captain of the rocket becomes aware of the asteroid and activates a warning signal. It takes one hour before...

A 0.00410–kg bullet traveling horizontally with a speed of 1.00 ✕ 103 m/s enters a 21.0–kg door, embedding itself 19.0 cm from the side opposite the hinges as in the figure below. The 1.00–m–wide door is free to swing on its hinges. (a) Before it hits the door, does the bullet have angular momentum relative to the door's axis of rotation? Yes or No Explain. (b) Is mechanical energy conserved in this collision? Answer without doing a calculation. Yes or...
