6. A 60 kg astronaut, floating freely in space, pushes forward with a force of 30 N on a freely floating satellite that hasa mass of 120 kg.(a) What is the value of the force exerted back on the astronaut by the satellite?(b) The astronaut will end up moving with a speed that is (faster, slower, the same as)the satellite after this force is applied.

The weight of an astronaut plus his space suit on the Moon is only 250 N. How much do they weigh on Earth? What is the mass on the Moon? On Earth?
. As a spacecraft approaches a planet, the rocket engines on it are fired (turned on) to slow it down so it will go into orbit around the planet. The spacecraft’s mass is 2.000 kg, and the thrust (force) of the rocket engines is 400 N. If its speed must be decreased by 1,000 m/s, how long must the engines be fired? (Ignore the change in the mass as the fuel is burned.)

2. A rocketship of mass mR = 2000 kg tows an asteroid full of valuable minerals with a mass mA = 500kg with a rope (space rope, or something). The two are out in the far reaches of space, so thegravitational force from the Earth and other planets can be ignored.The asteroid is under the influence of the force of tension from the rope. The rocket is also underthe influence of the rope’s force, and it’s also being thrust forward by the force of its engine. Therocket and asteroid both have an acceleration of 0.5 m/s2 (a) What is the strength of the force of the tension in the rope? (b) What is the strength of the engine’s force on the rocket, and in which direction does it point?

Scientists are experimenting with a kind of gun that may eventually be used to fire payloads directly into orbit. In one test, this gun accelerates a 7.6-kg projectile from rest to a speed of 5.1 × 103 m/s. The net force accelerating the projectile is 6.4 × 105 N. How much time is required for the projectile to come up to speed?
