Answer:
Explanation:
Maximum speed is get at maximum power. Let assume that ship travels at constant speed, the expression for power is equal to:
Where 
and 
are the forward force and speed of ship measured in newtons and meters per second, respectively.
The forward force can be determined by clearing it in the expression described above:
Supposing the runner is condensed to a point and moves upward at 2.2 m/s.
It takes a time = 2.2/g = 2.2/9.8 = 0.22 seconds to increase to max height.
Now looking at this condition in opposite - that is the runner is at max height and drops back to earth in 0.22 s (symmetry of this kind of motion).
From what height does any object take 0.22 s to fall to earth (supposing there is no air friction)?
d = 1/2gt²= (0.5)(9.8)(0.22)²= 0.24 m
