One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction. Suppose a satellite in a circular orbit 500 km above Earth’s surface collides with a pellet having mass 4.0 g. (a) What is the kinetic energy of the pellet in the reference frame of the satellite just before the collision? (b)What is the ratio of this kinetic energy to the kinetic energy of a 4.0 g bullet from a modern army rifle with a muzzle speed of 950 m/s?

Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 4.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle? (a) particle A --------- J(b) particle B --------- J

There is a large crater in Arizona called Meteor Crater. It is estimated that it was formed about 20,000 years ago by a meteorite that had a mass of about 5 x 10^10 kg and was traveling at a speed of 7.5 km/sec. How fast could this meteorite have hit the Earth (whose mass is 6 x 10^24 kg) if we assume a head-on collision?

An astronaut of mass 65.0 kg is at rest relative to her space vehicle with nothing behind her except the empty,dark, vacuum of space. Another astronaut decides to play a practical joke on her and throws a 10.0 kg anvil(because those are totally used in space) at her with a velocity of 3.00 m/s. How fast do she and the anvil moveonce she catches it? Just to lower your anxiety, there is a way for her to get back to the space vehicle

A space vehicle is traveling at 4450 km/h relative to the Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 64 km/h relative to the command module. The mass of the motor is four times the mass of the module. What is the speed (km/h) of the command module relative to Earth after the separation?

A 0.25 kg mass of clay is moving with a horizontal velocity of v when it collides and sticks to a 5 kg object hanging from the end of a 1 meter long rod. Find the minimum velocity v so that the objects will make one complete revolution.

3. Two asteroids collide and stick together. The first asteroid has mass of 15 × 10³ kg and is initially moving at 770 m/s. The second asteroid has mass of 20 × 10³ kg and is moving at 1020 m/s. Their initial velocities made an angle of 20° with respect to each other. What is the final speed and direction with respect to the velocity of the first asteroid? How much thermal energy is generated in the collision?

A saturn 5 rocket must travel 17, 800 mph to escape the gravitational pull of the earth and enter space. The rocket weight 6.2 million pounds, and the initial specific impulse lasts 263 seconds. What impulse is required for the rocket to meet the 17, 800 mph momentum in needs, using the formula FT=MV?

A space vehicle is traveling at 4130 km/h relative to Earth when the exhausted rocket motor is disengaged and sent backward. The relative speed between the motor and the command module is then 83 km/h. The mass of the motor is four times the mass of the module. What is the speed of the command module relative to Earth just after the separation? Number i Units

A space is traveling at 4300 km/hr relative to Earth. When the exhausted rocket motor is. disengaged. and sent backward with a speed of 82 km/hr relative to the command module. The mass of the rocket motor is 4 time the mass of the module. What is the speed of the command module relative to the earth just after the separation. Answer in km/hr.
