Answer:

Calculate the skid speed by multiplying the drag factor times the braking efficiency times the skid distance times 30 and taking the square root of the result. For example, if the car skidded 120.5 feet on a road with a drag factor of 0.5 and left four skid marks, the car was going about 42.51 mph.

Answer:

Solution given:

65mph

divide the speed value by 2.237

65/2.237=29.05m/s

So

speed =29.05 m/s

now we have

.speed =~30 d (0.5)

29.05/30=0.5d

d=0.96855/0.5

d=1.93

So

the length of the skid marks to be is 2 m.

78/14 Between which two consecutive whole numbers does this value lie? Enter your numbers in the box
Zigmanuir [339]

Given number is 78/14.

We have to find two whole numbers between which given number 78/14 lies.

Let's convert that into mixed fraction.

To do that we divide 78 by 14 to find the quotient.

We see that 14 goes 5 times into 78 and leaves remainder of 8.

So we can rewrite 78/14 as 5\frac{8}{14}.

5\frac{8}{14} means little more than 5 but less than 6.

So required two whole numbers are 5 and 6.
