A 2kg ball is rolled along the floor for 0.8 m at a constant speed of 6 m/s. What is the work done by gravity? A, 0
B, 16 J
C, 72 J
D, 450 J
E, 90 J

=F×s×cosa=2×g×0,8×cos90°= 0

work done=force×distance

=(2×10)×0.8

=16J

I hope this helps

  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.

what is the actual question though?
