A particle of mass 1
kg has potential energy, P. E.

=

3x+4y
. At

t

=0
, the particle is at rest at

(6,4)
. Work done by external force to displace the particle from rest to the point of crossing the x axis is :
-25 J
20 J
15 J
52 J

  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.
