Answer:
Explanation:
Given
coefficient of kinetic friction
mass of locomotive=180,000 kg
v=10 m/s
deceleration provided by friction
Time taken to stop completely is
v=u+at
where v=final velocity
u=initial velocity
a=acceleration
t=510.20 s
Distance traveled during this point
s=2551.02 m
In the 1970, the average American ate only 2 pounds of sugar a year. In 1970, we ate 123 pounds of sugar per year. Today, the average American consumes almost 152 pounds of sugar in one year. This is equal to 3 pounds (or 6 cups) of sugar consumed in one week!
