The only force acting on a 2.9 kg canister that is moving in an xy plane has a magnitude of 7.5 n. the canister initially has a velocity of 3.9 m/s in the positive x direction, and some time later has a velocity of 5.1 m/s in the positive y direction. how much work is done on the canister by the 7.5 n force during this time?

15.66 J

Explanation:

mass of block

Force magnitude=7.5 N

Initial velocity =

Final velocity=

Initial Kinetic Energy=

=

Final Kinetic Energy=

=

Work Done =Final -Initial Kinetic energy=37.714-22.056=15.66 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.
