Starting from a velocity of 0, your change in velocity over a period of 6 seconds will be ...
... (9.8 m/s²)×(6 s) = 58.8 m/s . . . . . downward, since you are "falling"
_____
Note the units of seconds in the time period cancel one of the factors of seconds in the acceleration to leave only seconds in the denominator of the result. That is confirmation that the proper math operation is being carried out, since the units of velocity are meters per second.
I am not sure but I do know that you need to have coordinates points in order to be able to graph... so there for you have to make an x/y chart in order to know here to graph...
Answer: the speed of the current is 9 mph.
Step-by-step explanation:
Let x represent the speed of the current.
A boat can travel 21 mph in still water. If it travels 270 miles with the current. It means that the total speed with which the boat travelled with the current is (21 + x) mph.
Time = distance/speed
Time spent by the boat in travelling 270 miles is
270/(21 + x)
In the same length of time, it travels 108 miles against the current. It means that the total speed with which the boat travelled against the current is (21 - x) mph.
Time = distance/speed
Time spent by the boat in travelling 108 miles is
108/(21 - x)
Since the time is the same, then
270/(21 + x) = 108/(21 - x)
270(21 - x) = 108(21 + x)
5670 - 270x = 2268 - 108x
108x + 270x = 5670 - 2268
378x = 3402
x = 3402/378
x = 9
