The four values of f correspond to the coefficient of friction for four road and tire conditions: an icy road, a very good road

with great tires, an asphalt road with fair tires, and a wet road with fair tires. Match the coefficients of friction to the appropriate conditions by looking at the braking distance required.

Answer:

The four values of f are given in part a of the question as

f= 0.30, 0.50, 0.70, 0.90

The answers to the question are

i. icy road, f = 0.3

ii. Very good road with great tires, f = 0.9

iii. Asphalt road with fair tires, f = 0.7

iv. Wet road with fair tires, f = 0.5  

Step-by-step explanation:

The braking distance is given by

d = \frac{v^2}{2g(f+G)} Where

d = Braking distance

f = Coefficient of friction

G = Constant = Grade of the road and

g = Acceleration due to gravity = 32.19 ft/s²

Where  v = 60 mph we have

d = \frac{7744}{64.4f+0.02} ft

Therefore for

f = 0.3,  d = 400.41 ft

f = 0.5,  d = 240.35 ft

f = 0.7,  d = 171.71 ft

f = 0.9,  d = 133.56 ft

From the breaking distance required we have

i. icy road, f = 0.3

ii. Very good road with great tires, f = 0.9

iii. Asphalt road with fair tires, f = 0.7

iv. Wet road with fair tires, f = 0.5

The length of the base of a triangle is twice its height. If the area of the triangle is 64 square​ kilometers, find the height.
frez [133]
Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height 
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8

In circle p what is the measure of arc ab
S_A_V [24]
Remember the arc is equal to the central angle, so ab will equal angle APB. they told you angle APB is a right angle, how many degrees is this? that is what ab will be also:)

In the similar triangles below, solve for the value of X.
Angelina_Jolie [31]

9514 1404 393

Answer:

  x = 8

Step-by-step explanation:

Corresponding segments are proportional.

  (3x +1)/10 = (7x -1)/22

  11(3x +1) = 5(7x -1) . . . . . . multiply by 110

  33x + 11 = 35x -5 . . . . . . eliminate parentheses

  16 = 2x . . . . . . . . . . . add 5-33x to both sides

  8 = x . . . . . . . . . . divide by 2
