Can you be more specific?

You are looking for √6,000,669.

You can use the calculator at this site to find a good approximation of this value.

I'm far more into math, then I am into physics, but I'll take a shot at this:

the formula for location is:  d  = -4.9t² + vt

If the velocity is  8.1  along the slope, the vertical component of this will be found by using sin:

    sin(20°)  =  v/8.1   --->   v = 2.770

The formula becomes:  d  = -4.9t² + 2.77t

Since this formula describes a parabola, the maximum point (the stopage point) is halfway between where the distance is 0 (when it starts) and where it again becomes 0.

Solve:  0  = -4.9t² + 2.77t     --->     0  =  t(-4.9t + 2.77)     --->  t = 0  and  t =  0.5653

Halfway between 0  and  0.5653  is  0.28 seconds.

Again, no guarantee.

7/9 - 5/13

To subtract common fractions, find a common denominator.

To find the common denominator for the denominators  9  and  13,  multiply them together.

9 x 13 = 117.

Now multiply both the numerator and denominator of the first fraction by  13  and the numerator and denominator of the second fraction by  9.

(7/9)·(13/13)  -  (5/13)·(9/9)                    Multiplying numerators times numerators                                                                                                                and denominators times denominators:

(91/117)  -  (45/117)                                Subtracting the numerators and placing that answer                                                                                                over the common denominator:

46/117

My suggestion to find square roots is to use the calculator at this site to find the values.

The value of phi is (1 + √5) / 2.

For a more complete explanation, research "golden ratio" or "golden section" on the internet.

Put  8  in for r in the formula:

C = 2·r

C = 2·8

C = 16 

This is almost the formula for circumference,  C = 2·π·r.

If you fraction is a common fraction, such as  3/5,  change this into  3 ÷ 5  and get  0.6

Sometimes, when you divide, you will get a repeating decimal; for instance,  

     4/7  =  4 ÷ 7  =  0.571428571428...       Just use as much of the number as you need.

If you have a mixed number, such as  14 5/8,  turn the fraction part, the  5/8  into a decimal,  .625  and 

write it as:  14.625

  0.353 353 353 353 ...             x  100     =     35. 335 335 335 335 ...

If you want a common fraction, or a mixed fraction for your answer:

Let    n  =  35. 335 335 335 335 ...               Now, multiply by 1000 (becasue 3 digits repeat):

1000 n  =  35 335. 335 335 335 ...               Subtract the original number:

   -    n  =        35. 335 335 335 335 ...                                                                                                      --------------------------------------------

  999 n  =  35 300.

        n  =  35300 / 999

10 x 10  = 100
