A 735-kg two-stage rocket is
traveling at a speed of 6.80×103 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 2.60×103 m/s relative to
each other along the original line of motion.

A 170 kg rocket is moving radially outward from the earth at an altitude of 180 km above the surface with a velocity of 3.5 km/sec. At this point, its final stage engine shuts off. 1) Ignoring any minor air resistance, what is the rocket's velocity 780 km above the surface of the earth?"; m/sec 2) Again ignoring any minor air resistance, what is the rocket's velocity 780 km above the surface of the earth if its mass were 340...

QB: The Rocket Equation The velocity of a rocket t seconds after liftoff from earth can be modeled by v(t) = -g*t - v_e * Ln( (m-r*t)/m ) where g = 9.8 m/s^2, the usual earth gravity value, v_e = exhaust velocity, 3000 m/s (the e here isn't related to 2.71828...) m = initial mass of the rocket+fuel: 30,000 kg r = rate of using fuel = 160 kg/s i) Find a formula for the acceleration function a(t) and graph...

A 975 kg two-stage rocket is traveling at a speed of 5.10×103 m/s with respect to Earth when a pre-designed explosion separates the rocket into two sections of equal mass that then move at a speed of 2.10×103 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? What are the direction of each section (relative to Earth) after the explosion? How much energy was supplied...

A rocket in outer space has a payload of 5055.6 kg and 1.542 . 105 kg of fuel. The rocket can expel propellant at a speed of 5.580 km/s. Assume that the rocket starts from rest, accelerates to its final velocity, and then begins its trip. How long will it take the rocket to travel a distance of 3.82. 103 km (approximately the distance between Earth and Moon)? Question A fire hose 4.54 cm in diameter is capable of spraying...

A 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 35 m/s2 for 31 s, then runs out of fuel. Ignore any air resistance effects. What is the rocket's maximum altitude? How long is the rocket in the air before hitting the ground? Express your answer with the appropriate units.

A 1627 kg weather rocket accelerates upward at 8.2 m/s2. It explodes 3.69 s after liftoff and breaks into two fragments, one twice as massive as the other. Photos reveal that the lighter fragment traveled straight up and reached a maximum height of 493 m. What were the speed of the heavier fragment just after the explosion?

4) The escape velocity on the surface of a planet is given by 2GM V= R 1 S where G = 6.67 x 10-11 m² kg :-2 is Newton's gravitational constant, M is the mass of the planet, and R is the radius of the planet. The escape velocity is the velocity you have to thrown an object so that it does not come back down (better hit the gym!). Write v...
