To solve this problem we will apply the definition of Newton's second law, which says that force is equivalent to body mass by acceleration. In this case the mass of the trailer is 325Kg and its acceleration is , so we will proceed to replace and multiply these values to find the net force on this object.
F= 698.75N
Under the reference system in which the direction of travel is the positive direction, the direction of the force will be positive.
Almost all telescopes have a circular mirror. The area of a circle is proportional to 
where 
is the radius of the circle, the constant of proportionality being 
Therefore the area of 150 meter telescope would be
times bigger than the area of the smaller (10 meter) telescope.
