23. A spacecraft is in orbit around the Earth, where if feels a gravitational force of magnitude F. At that moment, it is located a distance L away from the center of the Earth. Later, the spacecraft leaves orbit and travels away from the Earth to visit an asteroid which is passing by. When it reaches the asteroid, it is a distance 40L away from the center of the Earth. What is the force of gravity on the spacecraft from...

Chapter 6, Problem 20 Go An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 4.9 x 104 kg, and the force causes its speed to change from 7700 to 4600 m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.2 x 106 m determine the magnitude of the force. (a) Work-...

Suppose you are an astronaut on a spacewalk, far from any source of gravity. You find yourself floating alongside your spacecraft but 10 m away, with no propulsion system to get back to it. In your tool belt you have a hammer, a wrench, and a roll of duct tape. How can you get back to your spacecraft? a. Move like you are flying to the spaceship b. Move like you are swimming to the spaceship c. Throw the items...

An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 4.2× 104 kg, and the force causes its speed to change from 7100 to 4500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.3× 106 m determine the magnitude of the force.

An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 5.4× 104 kg, and the force causes its speed to change from 6500 to 4500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.4× 106 m determine the magnitude of the force.

Imagine an asteroid starting to move toward the Earth from an infinitely far distance and from rest. The speed of the asteroid when it reaches to a distance ? from the center of the Earth is ?1. It will have a speed of ?2 after it travels more and reaches to a distance ?/2from the center of the Earth. What is the ratio of ?2 and ?1? Prove your answer. Hint: Use work-kinetic energy theorem

Please tell me correct answer and explain!
An asteroid is moving with a speed v in space, very far from any massive objects. Newton's first law of motion says that the asteroid will slow down since there are no forces acting on the asteroid. the asteroid will speed up since there are no forces acting on the asteroid. o the asteroid will continue to move with a speed v since there are no forces acting on the asteroid. the asteroid...
