Un cuerpo de 180 kg se debe lanzar hacia una distancia de 25 m. ¿Qué valor tiene el trabajo que se realiza al lanzarlo?
dsp73

Answer:

45, 000 J o 45 KJ

Step-by-step explanation:

Recordemos que trabajo realizado = fuerza * distancia

En este caso, fuerza = peso del objeto

Por lo tanto, peso del objeto = 180 Kg * 10ms ^ 2 = 1800 N

Por eso;

Trabajo realizado = 1800 N * 25 m = 45, 000 J o 45 KJ

Find all of the points on the x-axis which are 6 units from the point (−1, 1).
anyanavicka [17]
All the points that are 6 units from (-1, 1) are those on the circle
  (x+1)^2 +(y-1)^2 = 36

For y=0, the two points of interest satisfy
  (x+1)^2 +1 = 36
  (x+1)^2 = 35 . . . . . . subtract 1
  x+1 = ±√35
  x = -1±√35

The points you seek are (-1-√35, 0) and (-1+√35, 0), about (-6.916, 0) and (4.916, 0).

Nicholas has a collection of books. He has 115 fantasy and science fiction books. These books are 46% of his collection. How man
Anit [1.1K]

Given that Nicholas has a 115 fantasy and science fiction books which is 46% of his collection.

Now we have to find what is total number of books in his collection.

Let number of books in Nicholas collection = x

then number of fantasy and science fiction books = 46% of x = 0.46x


We already know that he has 115 fantasy and science fiction books, so both values will be equal and give equation:

0.46x=115

now we can solve this equation to find the answer.

x=\frac{115}{0.46}

x= 250

Hence final answer is:

Nicholas has 250 books in his collection.
