Answer:
Explanation:
The force to which the object of mass <em>m</em> is attracted to a star of mass <em>M</em> while being at a distance <em>r</em> is:
Where is the gravitational constant.
Also, Newton's 2nd Law tells us that this object subject by that force will experiment an acceleration given by <em>F=ma.</em>
We have then:
Which means:
The object departs from rest () and travels a distance <em>d</em>, under an acceleration <em>a</em>, we can calculate its final velocity with the formula
, which for our case will be:
We assume <em>a</em> constant on the vecinity of the surface because d=0.025m is nothing compared with . With our values then we have:
