the largest airplane every build is the hughes h-4 hercules flying boat its 97.5 m wingspan is still 9.1 longer than the next largest plane ever to be built however because it is made of birch not spruce as its populare nickname the spruce goose would suggest the mass of the h-4 is 1.81 x 10^5 kg considerably lighter than any other giant plane. The h-4 was flown only once over a distance of about 1.6 km if the maximum gravitational potential energy associated with the h-4 was 3.78 x 10^7 j how high did it fly

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
