p O words Question 42 5 pts A spacecraft of mass 1600 kg has landed on a planet of mass 3.4 x 1012 kg, with a radius of 2.4 x 104 m. What is the gravitational field strength at the surface of the planet? In order to achieve vertical lift off with an acceleration of 7.5 m/s?, what thrust needs to be created by the spacecraft? Will this acceleration remain constant while the spacecraft travels away from the planet if this thrust is maintained? Why, or why not?

If the object was initially sliding with a speed of 0.75 m/s and the object that was motionless had a mass of 350 g, what would be the final velocity of the objects once they are stuck together?

An object that has a mass of 55 g compresses the spring 11 cm and then is let go. How fast is the object moving after the spring has pushed it 0.04 m? What is the fastest that the object will move while being pushed by the spring? The object loses contact with the spring at maximum speed. If an average force of friction of 1.0 N brings the object to a stop in 2.0 s, how far will the object have travelled after leaving the spring?
