1) In the early morning, a park ranger in a canoe is observing wildlife on the nearby shore. Earth's gravitational force on the ranger is 760 N downward, and its gravitational force on the boat is 190 N downward. The water
keeps the canoe afloat by exerting a 950 N force upward on it. Draw a free-body diagram of the canoe.

this a false

explanation:

  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.
