The last stage of a rocket, which is traveling at a speed of 8300 m/s, consists of two parts that are clamped together: a rocket case with a mass of 370 kg and a payload capsule with a mass of 140 kg. When the clamp is released, a compressed spring causes the two parts to separate (with the payload being propelled forward and the rocket case backward) with a relative speed of 720 m/s. What are the speeds of (a) the rocket case and (b) the payload after they have separated? Assume that all velocities are along the same line. Find the total kinetic energy of the two parts (c) before they seperate?
A space probe is traveling in outer space with a momentum that has a magnitude of 3.04 x 107 kg·m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.19 x 106 N and a direction opposite to the probe's motion. It fires for a period of 8.86 s. Determine the momentum of the probe after the retrorocket ceases to fire.
You go on a hot air balloon ride. The total mass of the balloon and the people riding in it is 1000 kg. At a height of 500 m, the balloon is rising straight up at a velocity of 10 m/s. The pilot drops 3 bags of sand out of the balloon basket. The new mass of the balloon and occupants is 850 kg. What is the velocity of the balloon after the sand is dumped?

- A single-stage rocket of mass 308 metric tons (not including fuel) carries a payload of 3150 kg to low-Earth orbit. The exhaust speed of the rockets cryogenic propellant is 3.20 103 m/s. a. If the speed of the rocket as it enters orbit is 8.00 km/s, what is the mass of propellant used during the rockets burn? b. The rocket is redesigned to boost its exhaust speed by a factor of two. What is the mass of propellant used in the redesigned rocket to carry the same payload to low-Earth orbit? c. Because the exhaust speed of the redesigned rocket is increased by a factor of two, why is the fuel consumption of the redesigned rocket not exactly half that of the original rocket?arrow_forwardTwo astronauts on opposite ends of a spaceship are comparing lunches. one has an apple, the other has an orange.

- A 1.0 ⋅ 104 kg spacecraft is traveling through space with a speed of 1200 m/s relative to Earth. A thruster fires for 2.0 min, exerting a continuous force of 25 kN on the spacecraft in a direction opposite the spacecraft’s motion. Calculate the initial momentum and the final momentum of the spacecraft.arrow_forwardA particle of mass m is moving at speed v=c/2. At what speed does the particle have double the momentum that it has at v=c/2?arrow_forwardWe know that the mass of the bagged lunch is m = 1.40 kg and the mass of the astronaut is M = 67.0 kg. Before the collision, the bagged lunch moves with a velocity of vi = 1.60 m/s in the positive x-direction and the astronaut is at rest relative to the space station with velocity Vi = 0. MVi + mvi = MVf + mvf to obtain (67.0 kg)(0 m/s) + (1.40 kg)(1.60 m/s) = (67.0 kg)Vf + (1.40 kg)vf. Because vf = Vf, this further simplifies to (67.0 kg)(0 m/s) + (1.40 kg)(1.60 m/s) = (1.40 kg + 67.0 kg)Vf. What is the velocity of the astronaut after the collision?arrow_forward

(a) The force on the Earth is greater than the apple- because the Earth is more massive. (b) The force on the apple and the Earth are 0 because they aren't touching. (c) The force on the apple is greater than the Earth- because the Earth is more massive. (d) The force on the apple and the Earth are equal.arrow_forwardA 100-kg astronaut finds himself separated from his spaceship by 10 m and moving away from the spaceship at 0.1 m/s.
