Now that you know the total skid distance (3.8 ft), use the skid-distance formula to find how fast the car was going before it s

tarted skidding. How fast was the car traveling before it started skidding? s= sqrt (30 * drag factor * skid distance * braking efficiency)
s= speed
drag factor= 0.90
skid distance= 3.8
braking efficiency= 80% or 0.80

Answer:

  9.1 mph

Step-by-step explanation:

Put the numbers in the formula and do the arithmetic.

  s = √(30×drag factor×skid distance×braking efficiency)

  s = √(30×0.90×3.8×0.80) = √82.08 ≈ 9.06

The car was traveling about 9.1 mph before it started skidding.

Pls solve question 8
s2008m [1.1K]

The value of the angle ∠AVB is 53°, side VB = 132.83 m, side OV = 119 m

<h3>How to find the side length from bearings?</h3>

8) From the given triangle we see that;

∠VAO = 37°

∠VBO = 64°

∠VOA = 90°

a) Now, we know that sum of angles in a triangle is 180°. Thus, for triangle AVO, we can say that;

∠VAO + ∠VOA  + ∠AVB = 180°

37 + 90 + ∠AVB = 180°

∠AVB = 180° - 127°

∠AVB = 53°

b) Using triangle rules we can say that;

tan 64 = VO/BO

Similarly, we can say that;

tan 37 = VO/(100 + BO)

Dividing both equations gives;

tan 64/tan 37 = (100 + BO)/BO

2.72BO = 100 + BO

1.72BO = 100

BO = 58.14 m

Using trigonometric ratio;

58.14/VB = cos 64

VB = 132.83 m

c) OV/132.83 = sin 64

OV = 132.83 * sin 64

OV = 119 m
