Answer:49 sec
Step-by-step explanation:
Given
Maximum speed to reach is 183.58 mi/h
Length of course is 5 mi
acceleration rate is defined by 60mi/h in 4 sec
therefore acceleration(a)![=\frac{v-u}{t}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bv-u%7D%7Bt%7D)
![a=\frac{60\times 60\times 60}{4}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B60%5Ctimes%2060%5Ctimes%2060%7D%7B4%7D)
![a=54\times 10^3 mi/h^2](https://tex.z-dn.net/?f=a%3D54%5Ctimes%2010%5E3%20mi%2Fh%5E2)
To reach a speed of 183.58mi/h with an acceleration of ![54\times 10^3 mi/h^2](https://tex.z-dn.net/?f=54%5Ctimes%2010%5E3%20mi%2Fh%5E2)
Using equation of motion
v=u+at
![183.58=0+(54\times 10^3)t](https://tex.z-dn.net/?f=183.58%3D0%2B%2854%5Ctimes%2010%5E3%29t)
![t=\frac{183.58}{54\times 10^3}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B183.58%7D%7B54%5Ctimes%2010%5E3%7D)
t=0.00339 hours
t=12.23 s reach maximum speed
To complete course it takes
![s=ut+\frac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2)
![5=0+\frac{1}{2}\times 54\times 10^3 \times t^2](https://tex.z-dn.net/?f=5%3D0%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%2054%5Ctimes%2010%5E3%20%5Ctimes%20t%5E2)
t=0.01360 hour
or ![t=48.98\approx 49 s](https://tex.z-dn.net/?f=t%3D48.98%5Capprox%2049%20s)
Answer:
Peter Jonathan Winston (March 18, 1958 – disappeared January 26, 1978) was an American chess player from New York City
Step-by-step explanation:
In late 1977, Winston attended a FIDE-rated tournament at Hunter College High School in New York City. Despite being one of the highest-rated players in the tournament, Winston lost all nine of his games. A few months later, on January 26, 1978, following further surprising game losses, Peter Winston vanished and was never heard from again. According to some sources, Winston's disappearance occurred when he left his home without money, identification, or luggage during a severe winter storm. Many chess players who were close to or acquainted with Winston claim that the champion chess player's mental health had deteriorated, along with his game performance, in the last few years of his life, and that the decline in his mental health may have led to his disappearance.
Answer:
b
Step-by-step explanation:
Certificates of deposit are only available to the bank's most proven and valuable customers, so the bank can afford to give a greater interest rate on them.
We are given the dimensions 10 feet length and 3 inches height. The volume of the rectangular portion is equal to $72.59 / $98 per cubic yard that is equal to 0.74 cubic yard. This is equal to 19.98 cubic feet. This means the width of the portion is equal to 8 feet.
Perimeter is the border around something...you add all the sides. So you you'll add 5+5=10 , 8+8=16 , and then you add 10+16=26. The answer is 26.
