Want this question answered?
1 knot = 1 nautical mile per hourtime = distance ÷ speed= 2110 nautical miles / 10 nautical miles/hour= 211 hours= 8 days 19 hours.As 1 knot is 1 nautical mile per hour: a unit of speed, 1 knot per hour would be a rate of change of speed, ie an acceleration.
Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.
If starting from rest, Distance = 1/2 (acceleration) x (time)2 . Otherwise, Distance = 1/2 (initial speed + final speed) x (time)
Average acceleration = (change in speed) / (time for the change) = (60 - 0) / (2.1) = 28.571 miles per hour per second, or 41.905 feet per second2 Using: (1 mile / hour - second) x (5,280- ft / mile) / (3,600 second / hour) = 1.4666 ft/sec2
If the car begins with zero speed, thenDistance = 1/2 (acceleration) x (time)2
-- negative average acceleration -- fatigue
These two are measurements of completely different things. A Knot is a measurement of speed (1 Knot = 1 Nautical mile/hour) and a G is the measuremet of gravity (1G = the natural force of gravity)

That depends what you want to compare. In any case, 3G is more acceleration than 1G.

Certainly. The figures in the question are correct. Acceleration of 72 m/s2 results in speed of 36 m/s after 1/2 sec.Similarly . . . the final distance can easily be less than the speed. Example: You can drive 100 mphand wind up only 5 miles away, if you drive for 1/20th of an hour.
It takes a looooooooooooooooooooooooong time! You're at "1g" when you're just sittin' around - 1g being 1x of the force of gravity. So at 1g, you're not really accelerating at all.Lets do the math and start with 1 g equal to 32 feet per second. Light speed equals 186,000 miles per second. It will take approximately 78 years to reach light speed.But there seems to be an error in these calculations! 32 feet per second is NOT an acceleration, but a constant velocity, so after 78 years you would still be at 32 ft per second!!! The term 1-G refers to the constant acceleration of EARTH gravity, that is 32 ft per second (squared) at sea level!!!!!! Now at that acceleration it would take about 51.7 weeks to reach light speed, that is if I used the acceleration calculator correctly. Good question though!
1 gram or 1 cg
Acceleration is change of speed / time, so in this case you have 90 miles per hour per second. While this is a valid unit of acceleration (a unit of distance divided by two time units), you may want to convert this to other units. Reminder: 1 hour = 3600 second; and 1 mile = 5280 feet.
If starting from rest, Distance = 1/2 (acceleration) x (time)2 . Otherwise, Distance = 1/2 (initial speed + final speed) x (time)
That speed is described as "fifty miles per hour".
1g is not a measure of speed. It may refer to 1 times the acceleration caused by gravity - but this is an acceleration, not a speed. It is about 9.8 meters per second per second, meaning that under normal gravity, the speed of a falling object increases by 9.8 meters/second every second.
