In boot camp, a cadet must use a rope swing to cross an obstacle without falling into the water hazard below. Unfortunately, the

horrorfan [7]

Answer:

3.04m

Step-by-step explanation:

Time taken to swing the rope = 3.5s

Length of the rope = L

T = 2π√(L / 9.8)

3.5 = 2π√(L / 9.8)

take the square of both sides

(3.5)² =[2π√(L/9.8)]²

12.25 = 39.48 × (L / 9.8)

12.25 = 39.48L / 9.8

39.48L = 12.25 × 9.8

39.48L = 120.05

L = 120.05 / 39.48

L = 3.04m

The length of the rope is 3.04m

WILL MARK BRAINIEST!!! Segment AC has two endpoints; (-2,5) and (2,-5). What are the coordinates of point B on segment AC such t

svet-max [94.6K]

Answer:

$(\frac{4}{3},-\frac{10}{3})$

Step-by-step explanation:

If the extreme ends of a line segment AC are A $(x_1,y_1)$ and C $(x_2,y_2)$ .

If a point B(x, y) divides the segment in the ratio of m : n

Then the coordinates of the point B are,

x = $\frac{mx_2+nx_1}{m+n}$

y = $\frac{my_2+ny_1}{m+n}$

If the ends of AC are A(-2, 5) and C(2, -5) and a point B divides it in the ratio of m : n = 5 : 1

Therefore, coordinates of this point will be,

x = $\frac{5\times (2)+1(-2)}{5+1}$

= $\frac{10-2}{5+1}$

= $\frac{8}{6}$

= $\frac{4}{3}$

y = $\frac{5\times (-5)+1(5)}{5+1}$

= $\frac{-25+5}{6}$

= $-\frac{20}{6}$

= $-\frac{10}{3}$

Therefore, coordinates of the point B are $(\frac{4}{3},-\frac{10}{3})$ .
