A spacecraft is traveling with a velocity of +3250 m/s. Suddenly the retrorockets are fired, and the spacecraft begins to slow d

own with an acceleration whose magnitude is 10.0 m/s2. How far does the spacecraft travel until it comes to a momentary halt?

Answer;

= 528 km

Explanation;

Assuming the question is how far would you be from the asteroid when your relative velocity is zero.  

The time taken to stop is 3250/10 = 325 secs  

and your average velocity is 3250/2  

So, the distance traveled is 3250 * 325 /2 = 528 km  

Alternatively;

- if you started with v^2 = 2as  

to get s = v^2/(2a) you get exactly the same calculation and of course the same result.

blondinia [14]

Answer: Enceladus

Explanation:

Enceladus is a small, icy body with an undergound ocean beneath its crust. Cassini discovered that geyser-like jets spew water vapor and ice particles. It is also the sixth largest moon in Saturn and just about a tenth of the largest moon in Saturn; Titan. It is often regarded as one of the most reflective body in the solar system as a result of its icy surface.

Benjamina started her walk from the front door of her ground floor apartment. She walked 6 meters to the corner of the building
Cloud [144]
The distance is the total distance she walked which is 16 meters adding the 6 meters to the corner and 10 meters to her friend's apartment. Her displacement is the distance from her original starting point so you set up a triangle with side lengths of 6 and 10 and solve for the hypotenuse which gives you a displacement of 11.66 meters.
