Arock is dropped from a bridge to the water below. it takes 3.2 s for the rock to hit the water. find the speed (in m/s) of the rock as it hits the water. how high (in m) is the bridge above the water

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

  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.
